How to find a good ground

07-04-2006, 04:13 PM
Well being the car novice I am slowly getting my auxgmv3 installed. Got the radio pulled, hooked up the auxgmv3 and got the dash put back together. I am now looking for a good ground my the glovebox or radio. Is there a way to use a multimeter to find a good ground close to the radio? Anyone know of a ground close to that point? I was thinking of checking resistance from a bolt at the door hinge to metal object behind the glove box.

2004 Trailblazer LT

P.S. I am still looking for the best switched fuse in the rear fuse box to use too.

Thanks ahead of time.
