Rear Wiring Harness ? Trailer Plug

[54blackhornet]

I have been working on the Safe Tee bumper last few days. While replacing the corroded 4 way plug I noticed it was never connected to the wiring harness. My question is, did the factory provide the wires needed inside the big wrapped area just before the grommet in the frame.

Here is an adapter i have used in the past for trailer lights
Is your truck a short box ?

Most likely that is is extra length taped up to create the bulge before the connector

I have not seen a factory spared pigtail yet in a back light harness on any on my 67 72 trucks

With some parts books you may have to say 79 c10
I rember doing that many times over the years for some parts i needed new drums for my 74 short box had to tell new parts guy at chevy well order me a set for a 79 c10
In 1989 chevy dropped the 74 part number and never added the supersed number to there listing
