Running Lights Wiring

[CARVAL Motorsports]

I will be a newbie to the toad/dinghy theater this summer. My RV is still in storage, and I am slowly aquiring the gear I will need. I recently purchased a used Falcon towbar and am trying to find used Roadmaster baseplates. I will be towing a Wrangler. The towbar came with a twin 4/hole coiled connecting wire. I have yet to research the wiring end of things, so I am starting here.
My 97 Dolphin is currently wired with a brake controller and a 7-way wiring coupler for the enclosed trailer I am usually hauling. I am correct to assume that I must just forget this wiring and that all wiring for the toad will just be done out of the tailights of the RV??? Is this correct, running to a 4 post male connector. Is this then done with the Jeep as well, all running forward to a 4 post male connector? Do diodes go into system at RV or at Toad? Wow... as you can see, LOST!!!!!!!!!! If anyone has (as someone always seems to) a saved wiring diagram and a list of all needed components, I would greatly appreciate it!

The harness you have will be used to connect between your coach and your Jeep, your Jeep will still have to be wired for the lights to work. Cool-Tech has a really neat and simple wiring harness to wire up your Jeep, I highly reccommend using this over other wiring methods. Your will need a 7 pin to 4 pin adapter, which you can get at just about any auto parts store, this will plug in to your coach. The harness you have will plug in to this adapter and then in to your Jeep. You will need a plug-in on the front of your Jeep to wire the Cool-Tech harness in to, this is where the harness from your coach will plug in. Sounds more complicated then it really is, actually it's pretty simple. You will find that a Jeep is a great toad. Don't forget about auxilary brakes for your Jeep, it is a law in most states, and a very important safety issue! There are many different kinds of braking systems with many different prices, most all of them work well, you can read all about them on this forum. Good luck with your project and Happy RVing! P.S. If you use the Cool-Tech harness you won't need any diodes anywhere.

Checked CoolTech website, seems the kit is only for the later JK model and not the TJ or earlier. :(

You can use standard trailer wiring (flat four wire) and wire your jeep, but you will need to use diodes to do this, it isn't hard to do, but it is a pain where the sun doesn't usually shine.

Roadmaster provides some good information on wiring under the Tech Support section of their web site. Scroll down to the wiring diagrams where they have schematics showing how to wire various lighting arrangements on both the motorhome and toad. They show wiring using diodes and the existing toad bulbs in several configurations as well as separate bulbs added to the tail light assemblies.
