Cig lighter/ashtray illumination
 

Can anybody verify for me please. The two reds/hots coming off of each of those. They run to the 4-pin connector. What color wire is running off the harness to those two red leads? My harness was all jacked up from previous owner radio install. I have a black wire coming off of the pin that goes to those hot leads but it’s cut. There isn’t a black wire like it that’s cut anywhere else?

In 1993 (which may or may not help you; you don't give a year) the 4 pin connector to the cigarette lighter (C3) has G to Lighting, W-G to the Rheostat, then to Ground, GR-R to the integration relay then to Cigarette fuse, and W-B to ground.

Rather than looking for a wire of a certain color, you might be better off looking for a connection to the correct function: Lighting, Rheostat, Cigarette fuse, and ground.

I’m no electronics engineer here. You have to make this simple. The two reds coming off of ashtray light and cig lighter light go into the same connection on the connector. What color is the wire coming from the chassis harness going into that connection?

or is there a diagram labeling wire colors and where they go that I can refer to?

I don't know. The EWD doesn't show the wire color from the connector to the lamp, just from the harness to the connector.

Engineer or not, I think you're going to have figure out what those red wires are, and what feed they need.

When I added the cig light and ashtray light in my 91 that was not hacked by PO I did not have an existing plug to fit, I ended up tapping into the lighting for my climate control. I also was looking at finding the column with the light but after not finding a plug for that anywhere I decided to deal with no light.
