Was wondering if anyone knew of any good aftermarket main battery ground wires being sold. Im looking to upgrade the dinky little main ground wire that comes off the battery and bolts to the strut tower with something a little bigger gauge with dual connections to both the body and the trans/engine for better grounding, however I cant exactly find any good upgrades, ive been looking at stuff from different cars but havent found much in what im looking for.

 

I made one to replace the valve cover to rad support myself out of thick stereo wire and connections.
Get a battery terminal, nice thick gauge wire, and a ground connection and get crafty.

 

Wire guage requirements vary by length. You can look up wire guage charts. These are short lengths and factory adequate. If you want to change, replacement with heavy stereo amp wiring, not speaker, or welding wire will work. You can buy it by the foot at some welding shops. with various heavy ends. This will work for battery relocation with long lengths if you follow guage requirements, for cars.
