Hey guys im new to the camaro family! i just bought a 1983 camaro a couple days ago and the RPM and water temp and some other gauges were working but the past 2 days they have stopped working. Ive looked at the wiring and i found a random green wire unconnected and im thinking thats why the gauges have stopped working. Can anyone help me on trying to fix this. Thanks! i am a noob so bare with me!

 

I'd start with inspecting/ replacing the gauges fuse above the driver side hush panel. The fuse is a 10A fuse. Most of the fuse panels white printed letters are worn off from age. The fuse you want is in the column of fuses all the way to the driver side. It is in the row towards the front most of the vehicle. There are a few female terminals in the fuse panel froward past the fuse you want that are there for tapping into power sources.

In regards to your green wire of question, can you please take a photo of it. It may be identifiable.

 

Thanks that seemed to do the trick !
