The parts supplied in the box were adiquate but we used different conectors to install instead. What we did was use T connectors which instead of cutting wires, these keep the conection of wires together while the third is tied in and making it more waterproof. We had to remove the battery, which you'll have to remove the wheel cover to get at two bolts. Also the line that goes to the idler in front of the engine should be rapped in a plastic flex cover to protect it crossing the engine. There is plenty of room for the wires, but the box must be installed in the cab, because it is not waterproof. Soldering and all that stuff made me nervous that's why I went with conectors which are a stronger way of holding wires together. I'm on my way up to Maine right now but I'll keep you updated. George
