trailer light wire help

In theory this works. anyone done this or know if it would or wouldnt work?
I want to splice into my existing tail lights on my 81 CJ8, run a 4-wire flat to the front of the jeep. This way I have a full complament of tail lights when driving my cj8, AND a full complment of tail lights when it is being flat towed and its plugged into the tow rig.

Won't work, but almost will. It's been discussed here before, so you might be able to find the thread with a full description of the problem and solution.

As I recall, you need to either put some diodes in the turn signal wires, or disconnect the rear harness when towing. That's not difficult - there's a connector in the general area of the parking brake pedal.

EVERYTHING's easy for the guy who doesn't have to do it.

Not a big deal to do. You will have to add diodes to the vehicle being towed. I did it on a YJ. Check the wire bundle that runs under the drivers door opening. Near the emergency brake is the easiest place to splice into the wires and mount the diodes. Check below links below for more info.

If I were to flat tow my Jeep more, I'd make up a trailer wire harness with a flat four connector in front and on the back end a plug that would go into the Jeep's rear harness. No splices or diodes to worry about. Neat, simple and foolproof. Being that I'm such a fool.
