Couple of wiring harness questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was cleaning up and replacing a few wires before I put it on ebay and was wondering what a few of the wires are. I looked at a diagram I have, but I couldn't find anything.

This is coming off my main harness, don't know what it is though.

Also this one. I know the tail light one, but what is the light green one?

I believe the top one is the heater plug and the bottom one is the reverse light power. On a truck with reverse lights, there is a single green wire that runs from the firewall to the rear tail light harness.

Thanks Tony. Does anyone have a picture of the backside of the fuse box?

Hey David,

Shoot, I could have taken a picture a few weeks ago when I had my fuse block dangling. But now it is nicely mounted with stainless bolts. What are you interested in knowing? I can nearly remember the whole thing.
