I have a 36 Ford pickup and have completed installation of the wiring kit. What I need to know now is how to properly ground it. I have the battery mounted between the bottom of the bed and the frame. I have the ground cable running from the battery to a shutoff switch that is mounted in the floor of the cab and then from the switch to the frame. If I do have to run a ground from the battery to the engine will a heavy gauge wire (maybe a #10) due instead of a full size cable?
Also, my battery is an Optima which lays on it's side and I use the connections with the female threads to hook up my trikle charger to. The threads are stripping out. Has anyone used Helacoils to fix this problem? Thanks.
