Gauges not working!

[civicspencer]

Ok I'm slowly fixing all my wiring problems I need to find which wire is the ground for the gauges. The reason why I think it's the ground is cuz I have had to ground the headlights and turn signals to get them to work, can any of you guys help me out
I have a 92 eg
Thanks

Take it to a mechanic who knows electrical aswell. Or electrical but i always gone to my dads mechanic who is a badass at electrical s**t. I got a eg6 btw.

I have taken it to a local well known family mechanic but he says it's "no good" that's why I took it upon myself in trying to fix it, if I fix my gauges I'll be happy cuz I can't tell how much gas I have, my speed or when I fool around what rpm I'm at
