is for the motor. HELP!? I'm aware that the big 3 is the (1 - ground to chassis 2 - Pos from battery terminal to alternator and fuse box 3 - ground from motor to chassis). All wires are being replaced with 0/1 gauge wires and secured to enhance the flow and current. I've heard that replacing other wires might be helpful as well; such as the transmission ground. Does anyone have any idea what other wires would be worth my time and money to replace? Most importantly, where is the ground wire currently attached to my motor???
