ok i've been warned at the track already, how should i run the wires 'cause i don't think the instructions that came with the switch to just interupt the pos batt cable with the switch will be adequet? do i just also run the alt batt wire back to the switch then back forward to the factory batt term on the firewall to basically interupt this circuit with the switch as well? again, sorry i'm a bit thick on this
