Default Re: Ignition switch wiring help

I think the dark green on the ignition sw is for when you turn the key to ACC the temp gauge would go to H. On a chevy the hot light will come on. This is to check the chevy light. If you want to check the gauge use it. I would not use it. If you left the ACC on for some time you could burn out the gauge. Just tape it up so it will not ground out.
If you look at the 4 pin panel connector on the wiring diagram you will see 20 L.GR 36 your truck could have this wire it’s for the chevy cold light.

One more thing, when you rewrap the wiring harness don’t use electrical tape use OEM factory wiring tape it will not stick to the wires. When you have a metal body clamp around the harness wrap Teas 51036 tape around the harness, it’s a cloth tape that has a high abrasion protection
