OK, I'm getting dizzy. I just recognized a problem and not understanding this stuff makes it more difficult. I have mag lights and I wired the 4 pin connector to the 7 pin plug as expected - LH stop and turn, RH stop and turn, tail lights and GROUND. Then, my mag lights plug into this 4 pin standard unit.
Now the problem. Using the 12V supply is not problem. BUT, what do I now do for the ground for this power supply. The ground connection in the 7 pin is already in use with the mag lights.
Given what I paid for the Limited for ease of towing I'm getting more and more PO'd with FCA. I contacted Jeep Cares a week or two back on this forum and the real was simply that they would not provide any help or advice on this issue of power to the Jeep from the MH for liability reasons. Just wonderful.
How do I solve this ground problem. I'm hoping my son will get back in the next day or two. Surely I can't just connect a second wire to the ground pin?

Now I just hit the switch and all is on/off. I all so purchased the RVi towed vehicle unit (yes I spent the $50 instead of making up my own!), the ordering process and Sam who I spoke with at the company was super. The unit is well made (US) and is very easy to install. Getting a 12V feed to the RVi unit was made a little more complicated in my case because I use a wireless toad light set up. The wireless transmitter uses a four blade plug so I have to use and adaptor off the 7 pin round plug on the motor home, I therefore had no way (at least to my weak mind) to access the live wire lug. I merely tagged into the live wire behind the MH plug and ran a two wire (live and ground) wire thru a new 4 pin round plug on the MH to a four pin round plug that I placed on the lower right corner of my license plate bracket (had to cut the plate just a little). Ran the live to the RVi unit and the ground to a ground lug on the jeep and all is perfect.
