7 Pin Trailer Plug
I'm looking for some assistance in installing a 7 way plug on my van.
The van is factory wired for towing.
I have a brake controller and cable to connect in the cab.
The issue is at the rear end.
I have a factory 4 way plug.
It's connected to a flat, two row plug at the frame.
That plug has 10 wires going in to it.
I can plug the 4 way into the connection on the 7 way. That leaves a few wires to connect to the factory wires.
After much searching, I cannot find a wire diagram that identifies these wires.
None of the diagrams I have found identifies them.
eTrailer suggested I just buy a kit, with basically bypasses it all.
Is there anyone here who can help with the id of these factory wires, or offer suggestions?
On a side note, a fuse id guid I down loaded some time back, identifies one of the relays in the under hood fuse as the relay for the starter relay (diesel only)
I moved it to the position for charging a trailer battery, figuring I didn't need it...not so. It powers the starter relay in the gas van as well.
TIA.

Well, I'm going to bypass the harness as they show on the eTrailer videos.
The wires on the factory connection just won't pan out.
On a side note, I was redoing two grounds to the frame, one of which went to the fuel pump diver, as the wires looked like they were discolored due to a high draw.
The ground that was not connected to the pump driver, looked very dark. I followed it back to the loom in order to find some clean stands, and in the loom, it looked as if the wire had melted.
When I opened the bundle, there were two insulated wires, and the ground looked like a wire that had burnt up from to many amps.
It turns out, the ground wire had no insulation, and was wrapped in a foil type tape. I'd not seen this before on a vehicle.
When I get the time, I intend to follow it to the front of the van to see what it is from.
