Hello all, I've recently purchased a Fass 150. Upon trying to install it I've run into a problem (I think). How does this thing hook up electrically? I've got the one cable that came with it. It's got the plug for the Fass end and two bare wires on the other end. According to the instructions I'm supposed to hook the bare wires to the + and - on the battery. This just doesn't seem right, how would it turn on/off? Any advice?
