Basically what can be removed or not needed
-transmisson: Remove the trans wires as well as the pnp switch. Keep the VSS.
-EGR: mounts in front of pass. head with a tube running from the exhaust manifold to the valve then into the intake behind the TB. This for 03 and earlier motors mostly.
-canister purge valve/lines: These run from the charcoal canister to a valve above the drivers valve cover then into the intake on top.
-Cats: catalytic converters you don't need them.
-Rear O2's: These are mounted behind the cats (2 each) and tell the PCM if the cats are working or not. you don't need these.
-Oil level sensor: It's on the pass. of oil pan. You can jumper the wires in the harness at that plug. I usually leave it hooked up.
-TB heater: Coolant tubes in the TB that move coolant through the TB to heat it. Just remove the lines from the TB and reconnect underneath it.
The harness can be reworked to remove these things and make it for a 3 or 4 wire hook up to the vehicle. Then have the PCM tuned to remove what you don't need.
Sensor locations (Gen III truck motor)
-MAP is on top of the intake, towards the rear.
-Knock sensors are under the intake but the connector is just to the driver side of the MAP sensor on the intake. (Gen IV motors are on the each side of the block)
-Coolant temp is in the front of the driver side cylinder head.
-Oil pressure is right next to the Cam sensor at the back block behind the intake.
-Low oil level mounted on the pass or oil pan
-EVAP purge solenoid The cylinder sticking out of the intake right in back of the throttle body is the EVAP purge solenoid.
-TPS and IAC are on the cable throttle body. IAC on top. DBW TB has no IAC.
-MAF and IAT are combined in the MAF located on the intake tube.
-Cam sensor Back of the block on Gen III motors and is mounted on the front of the timing cover on Gen IV motors.
-Crank Trigger Located on pass. of block inboard of the starter. Gen III motors are 24x wheel and Gen IV are 58x wheel (save for the early LS2's 05-06 these were Gen IV motors with E40 ECM and 24x wheel's). Black color is 24x reluctor and grey one is 58X reluctor
