I have been unable to get the rear fogs to work ..been to the dealer to starscan activate, wired to trailer hitch rear backup pin....My question is can I run new wires to the existing lights and then to the back/up pin on the 10 pin trailer harness which already has power at the pin without causing any problems...all relays and fuses are intact???? Anybody have concerns?

I just bought a 2007 srt8, installed a trailer hitch but the 4-prong trailer harness does not work for the turn signels. I found out the the are two missing relays in the large fuse box, I am meeting with the service manager monday to see if we can correct the problem. My trailer has lights but no L R signels. Great suv---I love it.

Thats funny because with the large majority of us having found that the relays were missing after attempting the rear fog mod, I had the dealer test my 4-pin connector at my second oil change because I actually needed it for towing. Mine worked fine. First thing that I thought would be missing and wasn't...I was happy.

Send a PM to Mango, I think in another thread he said he could make them for people.
