Cheaper than most. This controller is installed and working but required modifications to get it that way. Plug wires for relay control are way to short. Had to cut a slot the cover to get enough length to reach the trucks original connector. The lock tab isn't long enough to lock the connectors securely together. If you utilize the existing sensor wires on the truck the bolts will drop out the bottom as there are no plugs on the underside to retain the bolts while replacing the sensor or any wires once the controller is mounted on the vehicle. (Tape across the holes on the underside) Electrically it functions but the refit required to get it that way is the pits.
