Hello every one i have a charging question.. im planning on installing a second alt .i have the stock alt and a 240 amp alt off of a chevy cavalier id like to add to the pontiac bonneville. Both are gm alts just one is chevy and orignial is pontiac. What my question is ,is the stock alt has 1 wire coming out of it. The hi out put has 2 wires coming out of it. how would i use the second alt to hook into the first alt being it has 2 wires and the stock alt has one. how would i hook this alt up properly.. what does the one wire do over the one with 2 wires. Thanks any help appreciated..
