Random wire unplugged under dash what is it where does it go? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Have a green wire that looks newer than the rest of the wires hanging under the dash near the fuse panel. The only terminal I see on the panel without anything attached is the back up light prong. Is this wire for that?

I don't see a wire like that on my '72. Do your backup lights work? If not, try connecting it to a hot terminal and see if the backup lights come on.

They do so I’m not sure what it is or is for.

I don't agree. I would not just connect it to power without knowing for a fact where it goes. I recommend finding out for sure what is on the other end of the wire. Dig or hire somebody to dig.

I agree just wanted to see if anyone else had this random unplugged wire. It’s odd because the wiring harness is original and not butchered at all yet this random newer looking green wire is hanging there. I was thinking it may have been detached from where it was plugged by foot or pedal movement given its proximity to the pedals but not sure.

It is possible it was kicked loose, or unplugged by PO when whatever it was for removed prior to sale. The opposite end may not be insolated and cause issue if you just try and plug in. Find the termination first. Then decide if its worth leaving in place. Looks in good condition and might come in handy someday.

Doesn't look stock to me, but you can go here and look at the manuals for your year truck for that color of wire-

Is there anything electrical on the truck that isn't working?

Don't know about the green part of the wiring, but the connector terminal sure looks like the 12 V power wire to the factory radio.

In my photos it's the red wire that is the 12 V wire and connector plugged in to the other connector.

The other photo is the back of the radio wire the other connector plugs in to.
