Trailer Wiring Help

Altaoatao · 07-23-2008

I've been searching the threads and I'm still having problems figuring this out. Maybe someone can help?

I have an 08 T2 with factory hitch and wiring. While towing, I can't get the running lights, break lights or right signal to work. I am somehow getting the left turn signal, and that's it. I am towing a boat trailer with a 5 pin connector which I assume has LED lights (Not that savvy w/ this stuff). I am using the VW Touareg Hitch Wiring Socket and 7 Pin to 4/5 Pin Trailer Wiring Converter. Is there anything else I need to make this work?

The dealer has had the car for a day and can't figure it out. They are telling me to take it to a "trailer Hitch shop" which doesn't make any sense. Any advice that I can convey onto the dealership would be appreciated.

Thanks!
Adam

There are fixes for this,more so than when we had the problem in '04. I had to put a standard incandescent light in the trailer circuit to "trick" the Towrigs system to deliver juice to the lights. IF the system doesn't sense a draw the LEDs won't work. There are now resistor kits to fix this now. The answer is on this forum somewhere on those.

Thanks! The dealer ended up changing a fuse that was 15 amp and should have been 20 amp. This helped and got both turn signals and the break lights to work. Now I'll need to figure out how to get all of the running lights working. I'll check out your suggestion above. Thanks!
