MA Mopar was cheap in the ground area.if you are going for concourse - battery to head and head to fire wall. Stock fuel gauge grounds through the fuel line. If you are doing a show and go car. More grounds are better my 69 bee I got the largest negative cable I could find. I put the battery ground to block instead of head. The cable had a short whip lead. I used that to the radiator support for the headlights more on lights. The head to fire wall I made a thicker cable. I used a repro fuel sending unit and had a friend weld a 1/4 inch tab on it for the ground cable. The cable is screwed to a tad near tank. By passing the fuel line. Please read mad electric amp gauge bypass and headlight relays. We need to fix what MA Mopar did not. I did all the changes on my car and love it.
