Trailer Wiring connection

Trailer Wiring connection

Postby Up The Creek [OP] » March 29th 2012, 6:59am

Hello,

Does anyone know where I might find the connector for a 4 pin trailer wiring extension on a 1999 GMC safari. I don't see anything beneath the Jack on the passenger side.

Thanks

Martin

I've read that it's either in the right rear pillar, or behind the right rear side panel. When I installed my trailer harness I didn't bother to look. Mines a conversion van and either one would have been more work to take off than to just make my own connections. I drilled a hole on either side, ran the wire up to the tail lights, soldered & shrink wrapped the connections, and put RTV around the wire to seal the hole where it passes through the floor. It's been 4 years so far, no troubles. I didn't need to add a brake controller until last year, but when I replaced the carpet I ran several wires for future use at that time. I connected one of those, and I was up and running (and stopping) in no time.

Your truck may not have had that RPO if you can't find it hovering in the jack area. I have only had 2 trucks out of the 5 or 6

I've had that came with the factory pigtail. So, I would say "you're on yer own" No problem, though, just remove the trim ** on

the driver side at the rear door, to gain access to the wiring harness that goes to the rear light fixtures. You will find everthing

you need to hook into on the truck side of the light fixture. For ease of installation, I get a terminal strip from Radio Shack

that accepts a small screw driver to tighten down on the cut and stripped wires.
