1. all you have to do is wire one wire (probably red) to your stock horn wire and then hook the other wire to ground ( any bare metal spot on your car).
2. The boat horn has a power and ground. It has a ground because most boats are fiberglass and you need to run a ground wire also. Just hook the ground to the car frame and the positive to the horn wire.
