school me on how you run with the factory lights of the vehicle in tow
is there some harness to buy or are they splicing into the wiring how are the doing it?

find the rear tail light wires right, left, running... splice 'em using 3 diodes (available at RV supplies) and wire up a 4wire flat plug like you would a trailer. (4th wire is ground)

Seems easiest to just buy the movable wiring harness with the magnetic light units... See them all the time behind RV's.

the magnet lights dont always reach the back of the tow vehicle.


when testing your wiring, ground it first other wise it will drive you fawking nuts trying to figure it out by hooking them up one at a time.

the magnet lights dont always reach the back of the tow vehicle.

So build a jumper extention... still seems easier to me.

I had a fiberglass bodied Jeep and had to use the OEM lights. It worked out good with the diodes.

If you have room inside the tail light housing, Blue Ox makes a tail light kit where you add an additional tail light bulb. The wires from this bulb run up to the plug on the front, so that it becomes completely seperate system from the vehicle. We prefer to add the extra bulb rather than put in diodes, because diodes do fail. With the computer control systems, and everything else they have crammed into the steering column, burned out diodes have been known to take out some exspensive electronics.


Food for thought.

pretty simple...

make a 20' pig tail that has a 4 pin on both ends.. plug one end into the plug on the tow rig, and the other end to the rig your pulling, I've seen that done a few times.
On my BII when I flat towed it, I had the tail light harness connected to the firewall with a 4 pin plug, so I just unplugged it, and plugged in the extension harness to the truck, that also worked fine
