How do I hook up my trailer brake setup on my 94 c3500?
I have a Tekonsha Prodigy trailer brake system that was installed on my dually when I bought it. When I bought my trailer, I didn't ask many questions about the trailer brake setup...I just knew I needed brakes on the trailer. Here's what I got:
1994 C3500 with a 6 pin connector.(I'm using a 6pin-to-4pin adapter for the trailer lights). My trailer has the normal 4 pin connector with an extra unused white wire hanging from the connector. Then there's the one big wire(it's actually two separate wires wrapped in the same insulation...kinda like house wire). I've looked at the directions from Tekonsha and I've looked all over ebay, but I don't know what I need to make the brakes functional. Can somebody please point me in the right direction? Thanks.

Re: How do I hook up my trailer brake setup on my 94 c3500?
Ok, I found the wiring scheme for the controller. It shows a blue wire as the trailer connector. I think I found that wire, and it seems to be connected to my 6 pin connector. Would that mean that I should connect the trailer brake wire(big one on the trailer) to the white wire(unused) on the 4 pin connector? Then plug that into my 6pin-to-4pin adapter?

Re: How do I hook up my trailer brake setup on my 94 c3500?
If you only have a 4 pin connector on you're trailer you need a 7 pin to use the brakes , you should also have a breakaway switch and a battery to apply brakes in case of a breakaway
Are you sure it is a 6 pin plug on you're truck? should be a 7 pin . here is a wiring diagram. http://www.rverscorner.com/wiring/7pole.html Brake controller wiring http://www.etrailer.com/faq-brakecontroller.aspx

Yes, I have a round 6-pin plug on the bumper. About the battery - does the 12v wire get run to the positive side of the battery like an alternator wire would?

The trailer needs to be rewired since it only has a 4pin connector. The truck is already wired up with the 6pin plug, I just didn't know what to do with it. Yes that does help. Thanks.
