Last year I had trouble with the engine-to-frame ground (was blowing the ECM fuse repeatedly). At that time, I moved the two ECM grounds onto another intake stud on the engine, which already had another ground wire on it. (pass side) Problem solved.

This weekend, I ran a new ground from this engine stud to the frame, and also a new ground from the firewall to the frame.

Both new grounds mounted to existing frame ground mount. Now has two old and 2 new cables on it.

I left both old ground cables in place, cuz they are both mounted in really PITA places. Both look bad. Body to frame cable looks just about worthless.

My question concerns the existing body ground mounting stud on the firewall. Is this a comman ground collection point, like a bus bar, for all the stuff inside the cab, or is this just a stud on the firewall ?

I'm guessing it's just a stud on the firewall, and my new firewall ground is just as effective, as the original ground was when new.

Radio sounds better, fan and lights seem better, etc.
