I just did mine install in 1 hour and 20 minutes, that includes running wires from the Switches, into the engine compartment for future use. Two things to help you do this install; First, insert a long screwdriver into the hole in the rubber boot from the engine side into the cab. Do this for two reasons, one, made sure the path for the new wire is clear and unobstructed, second, while the screwdriver is installed, go into the cab and look were it is located, that way you have a idea were to look for the wire you are going to insert. Second, spray a little wire lube in the rubber boot to make the wire slide in easier. Make up a 4 wire harness and stick it in the rubber boot after you insert the power wire. You might as well extend the wires from the switches while you have everything apart.
