Can't find a good ground location.
 

Im wiring up a dash cam in my 11 mcs I havehe wiring all tucked away and ran down to the fuse box on the pass side. My only issue is I cannot find a good ground or any ground under the dash.

if you drill a hole into good metal and attach a sheet metal screw you have achieved a "good ground"

remember that in the basic automobile the body is the ground .......

Yeah I was just trying to keep it clean and simple but everything under thr dash on the pass side is all plastic.

There is a ground point next to the fuse box. Splice there if you want

Yeah, i found a ground point behind the trim that runs along the floor on the pass side.
