[FrankenRover]

I need the wiring schematic for a 97 NAS D90:

Wind Shield Wiper switch (all the wires including the washer)
Turn Signal switch including horn
Headlight switch (high low, etc).

I do not have access to the manual, or CD, so if someone has this info please email me personally at [email protected]

Would like examples like blue/green wire goes to what. Etc

Thanks for the help,

Bill R.

here is some info, Still looking for the diagram, however, tha diagram will do you zero good. It does not show how to hook up to the switch. You are best off looking at another D-90 for the wipers. As fro the other stuff, i will see what i can find.



OPERATION
Feed from the positive battery terminal is connected to the engine compartment
fuse box (C1217-1) by a brown wire. Current passes though fusible link 5
(C570-2) which is connected to the ignition switch (C28-1) by a brown wire.
With the ignition switch in position ’II’ (C90-1), a feed is supplied to fuse 17 and
18 of the passenger compartment fuse box (C581-13) on a white wire. Fuse 17
(C581-14) supplies power to the rear wash/wipe circuit, while fuse 18
(C581-16) supplies power to the front wash/wipe circuit.
Front Wipers and Washers
Fuse 18 of the passenger compartment fuse box (C581-16) supplies the front
wiper relay (C39-8) a feed on a green wire when the ignition switch is in
position ’II’.
Slow and Fast Speeds
Fuse 18 also provides a feed to the wash/wipe switch (C278-6) on a green
wire. Moving the switch to the slow speed position allows power to flow across
the switch (C278-1) to the wiper motor (C30-3) on a blue/light green wire. This
feed into the wiper motor also has to travel through an internal resistor. This
extra resistance causes the motor to operate at slow speed. The wiper motor is
earthed (C30-1) on a black wire.
Moving the wiper switch to the fast speed position allows power to flow through
the switch (C278-5) to the wiper motor (C30-5) on a red/light green wire. This
time the feed from the switch does not have to flow through the internal
resistor, causing the motor to operate at fast speed. Again, the motor is earthed
(C30-1) on a black wire.
Operating the flick wipe function outputs a feed from the wash/wipe switch
(C278-5) and onto the wiper motor (C30-5) for as long as the switch is held
against spring pressure. The wipers operate at fast speed.

Park Circuit
Positioning the wash/wipe switch to the ’off’ position cuts power to the wiper
motor on the blue/light green or red/light green wire. The park circuit operates
to return the wipers to their park position. The park switch (C30-4) is integral to
the wiper motor. It receives a feed from fuse 18 of the passenger compartment
fuse box (C581-16) on a green wire. The park switch is closed with the wipers
in any position other than their park position.
With the park switch closed, power flows across the switch (C30-2) to the front
wiper relay (C39-5) on a brown/light green wire. The front wiper relay (C39-2) is
connected to the wash/wipe switch (C278-4) by a yellow/light green wire.
Power flows through the wash/wipe switch (C278-1) to the wiper motor (C30-3)
on a blue/light green wire. The wiper motor is earthed (C30-1) on a black wire.
The wipers operate until their park position is reached and the park switch
opens, cutting the power supply to the wiper motor.
Intermittent Wipe
Moving the wash/wipe switch to the intermittent wipe position allows power to
flow across the switch (C278-3) to the front wiper relay (C39-1) on a
white/green wire. When this signal is received by the relay, it switches the route
to earth (C39-4) on and off approximately every 5 seconds on a black wire. An
intermittent feed is then supplied from the relay (C39-2) to the wash/wipe
switch (C278-4) on a yellow/light green wire. Power flows through the switch
(C278-1) and supplies the wiper motor (C30-3) on a blue/light green wire. The
wipers operate at slow speed.
Programmed Wash/Wipe
Depressing the end of the wash/wipe switch operates the programmed
wash/wipe function. The washer switch (C278-6) is supplied a feed by fuse 18
of the passenger compartment fuse box (C581-16) on a green wire. When the
switch is closed, power flows across the switch (C278-2) to the front wiper relay
(C39-6) and the windscreen washer pump (C8-2). Both are supplied a feed on
light green/black wires. The washer pump is earthed (C8-1) on a black wire.

 

[Puffdragon]

here is more

When the front wiper relay (C39-6) receives a feed from the wash/wipe switch
(C278-2), it outputs a feed (C39-2) back to the wash/wipe switch (C278-4) on a
yellow/light green wire. Power flows across the wash/wipe switch (C278-1) and
onto the wiper motor (C30-3), which operates at slow speed. When the washer
switch is released, the relay will operate the wipers for a further 3 cycles. Once
this has been completed, feed to the wash/wipe switch is cut by the relay and
the park circuit is initiated.
Rear Wiper
The rear wiper switch (C1197-1) is supplied a feed by fuse 17 of the passenger
compartment fuse box (C581-14) on a green wire. When the switch is in the
’on’ position (C1194-1), power is fed to the rear screen wiper motor (C388-2)
on a red/light green then brown/light green wire. The wiper motor is earthed
(C388-1) on a black wire.
Rear Park Circuit
Positioning the wiper switch to the ’off’ position cuts power to the rear wiper
motor on the red/light green then brown/light green wire. The park circuit
operates to return the wiper to its park position. The park switch (C1105-2) is
integral to the wiper motor. It receives a feed from fuse 17 (C581-14) of the
passenger compartment fuse box on a green wire. The park switch is closed
with the wiper in any position except its park position.
With the park switch closed, power flows across the switch (C1105-1) to the
wiper switch (C1195-1) on a brown/light green wire. Power flows across the
wiper switch (C1194-1) back to the wiper motor (C388-2) on a red/light green
then brown/light green wire. The wiper motor is earthed (C388-1) on a black
wire.
Rear Wash
The rear washer switch (C1197-1) is supplied a feed by fuse 17 of the
passenger compartment fuse box (C581-14) on a green wire. When the switch
is depressed power is fed (C1196-1) to the rear screen washer pump (C21-2)
on a black/light green wire. The washer pump is earthed (C21-1) on a black
wire. The rear screen wash does not operate the rear wiper.

 

[Serious One]

Here's what I did...

Wow. Did you type that from memory KC??? :flipoff2:

When I wired my wiper motor I looked at that funky 5-wire loom and scratched my head...a LOT! I decided that simple was good and got a 3-position toggle switch and figured out which lead was for fast and which lead was for slow, and which was ground.

Just wired up the two speeds and left the other two wires intact on the odd chance that someday I'd get really ambitious and go for the factory installation.

I have no 'park' so to speak, except for the uncanny ability to recognize where I want them to stop wagging and turn off the power to the motor at just the right instant allowing for the motor to spin down and move the wiper arms just a little bit until they're just in the right factory-looking park position.

Whew. Still with me?

Anyway, I'm going to archive KC's directions. Now that I know what he's talking about and have done the wiring recently it makes more sense than just blindly staring at them.

Thanks man!

What you gonna do Bill? :flipoff2:

more for ya bill

EXTERIOR LAMPS - Indicators / Hazard Warning Lamps
DESCRIPTION
The indicators are controlled from the steering column switch and operate
when the ignition switch is in position ’II’.
The hazard lamp switch is located to the right of the steering column, adjacent
the rear fog lamp switch. Hazard operation is not dependent on the position of
the ignition switch. When the hazard switch is depressed, both left and right
hand indicator lamps flash.
OPERATION
Feed from the positive battery terminal is connected to the engine compartment
fuse box (C1217-1) by a brown wire. Power flows through fusible link 5 and
fuse 5, which are connected in parallel. Fusible link 5 (C570-2) provides a feed
to the ignition switch (C28-1) on a brown wire. Fuse 5 (C574-3) provides a
permanent battery feed to the hazard warning switch (C96-7) on a
brown/purple wire.
Indicators
With the ignition switch in position ’II’, power flows across the ignition switch
(C90-1) to fuse 17 of the passenger compartment fuse box (C581-13) on a
white wire. Fuse 17 (C581-14) is connected to the hazard warning switch
(C96-8) by a green wire. With the hazard warning switch in the off position,
power flows through the switch (C96-5) and up to the flasher unit (C536-6) on a
light green wire. The flasher unit is earthed (C536-4) on a black wire. With the
flasher unit energised, a feed (C536-8) is sent to the column switch (C36-3) on
a light green/brown wire.


Left Turn
Moving the column switch to the left turn position, allows power to flow across
the switch (C36-4) to:
• The LH trailer pick-up (C1149-1).
• The LH rear indicator lamp (C928-2).
• The LH front indicator lamp (C1-2).
• The LH side repeater lamp (C13-1).
• The LH indicator instrument pack warning lamp (C230-5).
All are supplied a feed on green/red wires, and earthed on black wires. With
the flasher circuit complete, the flasher unit commences opening and closing
the circuit, causing the LH indicator lamps to flash.
Right Turn
Moving the column switch to the right turn position allows power to flow across
the switch (C36-2) to:
• The RH trailer pick-up (C1151-1).
• The RH rear indicator lamp (C837-2).
• The RH front indicator lamp (C2-2).
• The RH side repeater lamp (C12-1).
• The RH indicator instrument pack warning lamp (C233-7).
All are supplied a feed on green/white wires and earthed on black wires. With
the flasher circuit complete, the flasher unit commences opening and closing
the circuit, causing the RH indicator lamps to flash.

Hazards
The hazard warning switch (C96-7) is supplied with a permanent battery feed
from fuse 5 of the engine compartment fuse box (C574-3) on a brown/purple
wire. Pressing the switch to the on position allows power to flow across the
switch (C96-5) to the direction indicator relay (C536-6) on a light green wire.
The energised relay is now able to provide a feed (C536-8) for both the LH and
RH indicator circuits on a light green/brown wire. The relay is connected to the
following via the hazard warning switch:
• The front LH indicator (C1-2) on a green/red wire.
• The LH side repeater (C13-1) on a green/red wire.
• The LH trailer pick-up (C1149-1) on a green/red wire.
• The rear LH indicator (C928-2) on a green/red wire.
• The front RH indicator (C2-2) on a green/white wire.
• The RH side repeater (C12-1) on a green/white wire.
• The RH trailer pick-up (C1151-1) on a green/white wire.
• The rear RH indicator (C837-2) on a green/white wire.
The hazard warning switch also provides a feed for the following warning
lamps:
• The hazard warning lamp (C1037-1) on a brown/red wire.
• The LH indicator warning lamp (C230-5) on a green/red wire.
• The RH indicator warning lamp (C233-7) on a green/white wire.
With the direction indicator relay energised, the circuit is repeatedly open and
closed, causing all indicators and warning lamps to flash.

and the head etc.

EXTERIOR LAMPS - Head, Side and Number Plate Lamps
DESCRIPTION
The lights are operated from the lighting switch located on the steering column.
The lighting switch has two positions. Position 1 switches on the tail lamps, the
number plate lamps, and the front side lamps. Position 2 additionally switches
on the front headlamps. When the headlamps are on, the column switch can be
used to switch between main beam and dipped beam.
The headlamps can be flashed with the lights on or off, by pulling the column
switch towards the driver.
OPERATION
Feed from the positive battery terminal is connected to the engine compartment
fuse box (C1217-1) by a brown wire. Current passes through fusible link 1,
fusible link 5, and fusible link 6, which are all connected in parallel.
Side Lamps
Fusible link 6 (C572-3) is connected to the lighting switch (C41-1) by a brown
wire. With the lighting switch in position 1, current flows across the switch
(C41-2) to fuse 11 and 12 (C581-1) of the passenger compartment fuse box.
Fuse 11 (C581-2) supplies the LH side of the vehicle, while fuse 12 (C581-4)
supplies the RH side of the vehicle.
Current flows from fuse 11 (C581-2) to the LH front side lamp (C538-2) on a
red/black wire. The side lamp is earthed (C538-1) on a black wire. Connected
in parallel with the side lamp is the trailer pick-up (C1189-1), which is also
supplied a feed on a red/black wire. The trailer pick-up (C1189-2) is connected
in series with the LH tail lamp (C121-3) by a red/black wire. The tail lamp is
earthed (C121-1) on a black wire. Wired in parallel with the LH tail lamp is the
rear number plate lamp (C138-1). Again, current is supplied on a red/black
wire. The lamp is earthed (C1190-1) on a black wire.

The RH side of the vehicle operates in much the same way. Fuse 12 (C581-4)
supplies a feed to the RH front side lamp (C537-2) on a red/orange wire. The
side lamp is earthed (C537-1) is earthed on a black wire. Connected in parallel
with the side lamp is the trailer pick-up (C1144-1), which is also supplied a feed
on a red/orange wire. The trailer pick-up (C1144-2) is connected to the RH tail
lamp (C125-3), again on a red/orange wire. The lamp is earthed (C125-1) on a
black wire.
Fuse 12 of the passenger compartment fuse box (581-4) also supplies a feed
to the instrument pack warning lamp (C230-8) on a red/orange wire. The
warning lamp is earthed (C230-4) on a black wire.
Headlamps
With the lighting switch in position 2, power flows through the switch (C41-4) to
the headlamp relay (C282-87) on a blue/yellow wire. The headlamp relay will
not be energised unless the ignition switch is in position ’II’.
Dipped Beam
With the ignition switch in position ’II’ current flows across the switch (C90-1) to
fuse 1 of the passenger compartment fuse box (C580-1) on a white wire. Fuse
1 (C580-2) supplies a feed to the headlamp relay coil (C282-85) on a
white/green wire. The relay is earthed (C282-86) on a black wire. This feed
energises the headlamp relay.
The lighting switch (C41-4) is now able to supply a feed to both the column
switch (C36-1) and fuse 6 of the passenger compartment fuse box (C580-11)
on blue wires. Fuse 6 (C580-12) supplies a feed to the fog ECU (C543-2) on a
blue/purple wire.
With the column switch in the dipped beam position, current flows from the
switch (C36-6) to fuses 7 and 8 (C580-13) of the passenger compartment fuse
box on a blue/red wire. Fuse 7 (C580-14) supplies a feed to the RH headlamp
dipped beam bulb (C11-2) on a blue/black wire. The lamp is earthed (C11-3)
on a black wire. Fuse 8 (C580-16) supplies a feed to the LH headlamp dipped
beam bulb (C9-2) on a blue/pink wire. The lamp is earthed (C9-3) on a black
wire.


Main Beam
When the column switch is moved to the main beam position, current flows
from the switch (C36-5) to fuses 9 and 10 (C580-17) of the passenger
compartment fuse box, and the main beam warning lamp (C230-6) in the
instrument pack. All are connected by blue/white wires.
Fuse 9 (C580-18) supplies a feed to the RH headlamp main beam bulb (C11-1)
on a blue/orange wire. Fuse 10 (C580-20) supplies a feed to the LH headlamp
main beam bulb (C9-1) on a blue/slate wire. Both lamps (C11-3 & C9-3
respectively) are earthed on black wires.
Headlamp Flash
Fuse 2 of the engine compartment fuse box (C573-3) supplies a constant
battery feed to the column switch (C36-7) on a purple wire. When the column
switch is pulled back to the flash position, it allows this current to flow along the
main beam circuit as described in the ’Main Beam’ description.

And, i have never seen this option. Kinda cool





EXTERIOR LAMPS - Headlamp Levelling
DESCRIPTION
To prevent dazzling oncoming drivers, the headlamps can be adjusted to
compensate for the effect of different loads on headlamp vertical alignment.
Headlamp levelling is controlled by a four position switch mounted in the centre
of the fascia, which operates a levelling motor on each headlamp. Nominal
vehicle loads for each switch position are as follows:
• 0 - Driver or driver and front passenger only; no luggage.
• 1 - All seats occupied; no luggage.
• 2 - All seats occupied; full luggage compartment.
• 3 - Driver only; full luggage compartment.
Headlamp levelling operates while the side lamps or headlamps are on.
OPERATION
Feed from the positive battery terminal is connected to fusible link 6 of the
engine compartment fuse box (C1217-1) on a brown wire. Fusible link 6
supplies a feed to the lighting switch (C41-1) on a brown wire.
With the lighting switch in either the side or main beam position, current is
allowed to flow from the switch (C41-2) to fuse 12 of the passenger
compartment fuse box (C581-1) on a red wire. Fuse 12 (C581-4) supplies a
feed to the LH headlamp levelling motor (C71-1), the RH headlamp levelling
motor (C70-1), and the headlamp levelling switch (C93-4). All 3 are connected
in parallel and are supplied a feed on red/orange wires. Fuse 12 also supplies
a feed to the headlamp levelling switch illumination bulb (C93-5), again on a
red/orange wire. All are earthed on black wires.
At each of the four switch positions, the contacts in the headlamp levelling
switch connect to a different resistance value to provide one of four different
output voltages. The output voltage (C93-2) is supplied to the LH (C71-3) and
RH (C70-3) levelling motors on blue/yellow wires. The motors are earthed
(C71-2 & C70-2 respectively) on black wires.
The difference between the voltage from the headlamp levelling switch and
battery voltage is then used by electronics in the headlamp levelling motors to
set the headlamps to a position corresponding to the switch position.
