Left Tail Light Wire Harness

[ramack]

79 K5
Looking for the complete section from the plug to the lamp sockets. A couple wires have broken at the base of the rubber plug. So I'm looking for a replacement, but thinking I may have to "repair" it as I'm running out of ideas for a source of the harness. And since it's broken of slightly below the surface, that going to make it tricky.

This is the last section on the drivers side from the fuel tank to the tail light sockets. I'll email a couple wire harness companies tomorrow, but so far I'm only finding the "intermediate" section that connects to the short section I'm looking for.

This guy repaired the section I'm working on, looks like getting the wire out of the rubber plug may be doable.

I’ve never had to do this repair, but from reading the link you posted it seems as though you need to feed a wire through a rubber socket. He described as having to push and pull the wire through. What you could do is slip a short solid brass tube over the wire (including the insulation) and solder the end of the wire to the tube. Then lube the brass and it should easily pull through the rubber. You can find the brass tubing at any hardware store where they sell raw metal. I’ve seen it at Lowe’s and HD, just can’t find it on their site. Here’s what I’m talking about:

Yes, that how I interpreted his fix too. It looked like the plug was molded over the pigtail, but after finding that thread, sounds like the wires just pushed through the rubber plug. This side of the plug has female spade connectors in the plug and there's not much to grip on, so your tube idea might work well just to push out the broken wire and female connector.

Thanks for the idea.

If the socket you need is the same as the one where the harness has a plug along the frame rail,you could get one of those trailer hitch "T" splicers that let you add a hitch plug without cutting the harness,and use the sockets & wires off that to repair your original harness..

What year? I have complete taillight harness available from a 75 pickup.

79 K5, driver side. I think 75 is different, buy might be wrong.

The harness covers both sides and the only difference is at some point they changed the plug from a 4 pin round connector to a 4 pin square connector. This one is a round connector.

Yeah, that's a different harness. I'll try to repair this socket and connection when it warms up. This is a 4-pin round connector.
