Re: Grounding the dash w/\'glass tub ?
I just recently finished up wiring my 'glass CJ-5 project. Rather than drilling more holes through the firewall, I ran a ground wire to the back of one of the bolts on the clutch and brake bracket. Then, on the engine side of the firewall, I ran a wire from the - post on the battery with leads to heater box stud, brake bracket, windshield washer, horn, ect. The ground wire is tucked neatly into the factory plastic loom. I was able to remove a lot of wiring under the hood with only one wire going to the Chevy hei distributor and Delco one-wire conversion alternator. When it comes to wires, I always like clean simplicity.
