Using this K - Tuned ground strap pair is easy. First, find the transmission and the chassis of your vehicle. Connect one of the 11 - foot long ground wires from the transmission to a bare metal part of the chassis. Then, connect the other wire from the engine to another bare metal spot on the chassis. When making the connections, ensure that the metal is clean and free of rust or paint to get a good electrical connection. As for maintenance, regularly check the connections to make sure they are tight. If you notice any signs of corrosion on the wires or connections, clean them with a wire brush. This will help keep your electrical system in good working order and ensure the best performance of your vehicle.
