What grounds the rallye dash?

[pauls340]

I've heard the screws that mount the dash to the dash frame is the ground??? Maybe that's why no dash lights, I painted the frame before I put it back together. HELP

there should be a black wire that grounds to the steering column and there should also be a voltage limiter with ground from cluster that plugs in with it.

fwiw
