New Harness & Wiring Questions
greenacres:
I am installing a new wiring harness in my 79 K10. I’m not replacing an existing wiring harness. There are only bits and pieces of the original wiring harness left. I have a wiring schematic and I’m pretty good at reading wiring schematics. My problem is there are some connectors on the new wiring harness under the dash that I can’t figure out what they are for or what they plug into.
Attached are some photos of the wires I can’t figure out. I think one of those connectors goes to a seat belt buzzer, but I’m not sure which one. Any help would be greatly appreciated.

Just glancing at the posted images, the connectors in images 1 & 2 plug up to the ignition switch. Images 3 & 4 connect to the brake lamp switch (left & upper) and radio (right & lower), respectively. Image 5 is a generic Series 56 connector used for various applications. Without seeing the wire colors there is a certain amount of guesswork.

Thanks bd. I'll see if that works.

You are correct about the wires to the brake light switch.
I assume you are right about the wires to the radio, and I assume I can use those wires for my little stereo CD player.
I have already plugged one large connector into the ignition switch and it has all the correct wire colors. Therefore I don’t see how those other two connectors can go there.
The white connector has wire colors: yellow, brown, pink, light violet.
The black connector has wire colors: orange, pink, black with white stripe, brown with white stripe.

The ignition switch uses two interlocking connectors, each connector pair is bi-colored (white/black, or less frequently, blue/black). IIRC, the black connector must be plugged into the switch before its switchmate. If you have only ONE connector already attached to the ignition switch, something is wrong. Post a pic of the connector you currently have attached to the ignition switch.
