    Ok, working on a 66 C10 and I have pn 52-662 hooked up to the lights. What harness do I need to from from the ends of this harness up to the front of the vehicle?

    I've looked at 52-623 but the connectors are round on this an 52-662 has square connectors....

    So which one do I need?

    Tailight Harness

    O.K. , I assume # 52-662 is the sub harness to the taillights at the back of the truck ? . (pix or link to pix helps a lot here)

    It's been a few years since I worked on a '66 but , IIRC the harness you're looking for is part of the main cab wiring loom / harness from the firewall ~

    Perhaps a copy of the harness and plug you have , will help folks decipher what you need .

    GM didn't change the connectors much over the years and I'm always cruising the yards looking for '69 C/10 parts so maybe a good used harness and plug can be located for you to splice into your existing loom ? .

    Others here have up graded to fancy-schmancy Hot Rod harness' and may sell you their old one affordably .

    I hope this is helpful , let's try to help a newbie 0out here ! .

    Nate,
    sorry about the lack of pictures. Lets see if this works.

    here's what I have connected to the light sockets PN 52-662:

    you can see the square plugs that go to another harness as you move forward towards the fire wall.

    Here is what I believe to be the next part of the harness which according to the website, goes from the firewall to the rear of the truck PN 52-623:

    It looks to me like this is a round connector where the tail light harness is a square connector. Is there something that 'marries' these two together? Thanks for the help!

    Bob the round plug appearance outside is actually square on the inside, I`m looking at mine right now.

    Why the Vendor didn't take decent photos , escapes me , they don't have any hands on people in the artworks department I guess .
