Well, as you can read, there's a few ideas out there and, people set up toad light wiring, as they see fit. I've utilized the stock tail lights in 11 toads now for over 30 years and have not had one single issue in doing it that way, EVER!
I do it that way because, the Jeeps tail lights act perfectly normal, when someone is following it and I'm towing it. They don't see conflicting signals that can, and often do happen with the installation of additional bulbs and sockets are used.
Every Jeep wrangler, including Jeeps from the earliest CJs, YJs, TJs and on through the JKs, all run the tail light wiring, right along the drivers left leg, under the door jamb. When doing mine and several other friends Jeeps, I simply run the wires from the plug on the front of the Jeep, to that point right at that door jamb. Then, I simply find the R/T/brake wire, LT/Brake wire and, running light wire and, tie into them. There are only two diodes to install at that point, one in front of the R/T Brake connection and, one in front of the LT/Brake connection, DONE!
There is no need to diode any other section of the wiring. Some will insist that a diode be place in the running light wiring so that, if the toad lights are activated by a driver BEFORE disconnecting from the coach, that the back-feed will damage the coaches lighting, HOGWASH!!!
We've done that, oh, probably a few dozen times. BIG DEAL. Anyway, unless you screw something up, there's litterally no way of damaging the toads wiring or lighting system if you do it this way. And, like stated, your Jeeps tail lights act the same exact way when towing it, as they do when driving it. And, there's no need to buy those fancy ultra high priced diode kits from Camping World or any other RV supplies outlet. I just use about $3,00 worth of diodes from Radio shack that work flawlessly. Your choice.
