Wiring up a 6AL box under the dash of my Caprice. Found a perfect spot for it to fit and I've figured out how to run most of the wiring. But, one little problem is where to ground the unit. I don't really want to run a long wire up to the battery for the ground...is there a better spot to ground it? I'm thinking that grounding it somewhere on the dash probably isn't the best idea...anyone done something similar?
