I don't know why either, Rough Country is loosing some money by not doing that, majority of us is looking for a wireless option like the factory set up, it works perfectly fine, the only thing I had to do was extend the wires from the solenoid box to the Winch and the 12v power lead, also I used the provided bracket to relocate the solenoid box and I put it exactly where is supposed to go, it was a tight fit but it sure works, took me and my buddy about 3 hours start to finish, most of the time was extending the wires and routing them to hide them and make everything looks factory... if anybody wants to do this mod and is close to Redlands CA and want to take the drive to my house I'm more than happy to help you guys!
