So I'm adding some switches and lights to my dash and I'm trying to figure out a good ground. I hav my dash out of the jeep on a bench, and I have grounds to my dash for my lights. Now when I test to see if my lights I put in my dash will work, I get nothing. I heard that I can ground to the dash but the dash grounds to the body. So when I re install my dash will the grounds I have set to my dash work?
If I understand your question, you have installed the lights and then grounded them to the dash while its on the bench? If that's the case, your dash is not grounded at that point so you'll need another temp bench ground for your dash to test the lights- maybe run a wire with alligator clips from the dash to your battery temporarily. Once the dash is back in, you'll have your ground back. Additionally, you can also run a dedicated ground from the battery to the dash for accessories if you like.

Yes, you won't have a ground until your dash is reinstalled. For testing, just ground it out to something else for now. Once the dash is back in you can also run a dedicated ground from the battery to the dash for accessories if you like.
What he said. I'm in the process of doing a rewire and have run dedicated grounds to my front (for headlights), my dash (for gauges, etc) and to the rear (for taillights and fuel sender).
This way I know my grounds are good - I've learned that a bad ground is the biggest culprit for electrical issues in a CJ.
