I bought this while rewiring my boat trailer after converting from drum brakes to disc brakes. Disc brakes require a 5 wire connector as the extra wire is used for the backup solenoid. The backup solenoid shuts off hydraulic pressure so the trailer brakes are not applied when reversing. The great thing is that this 5-wire connector mates properly with a 4-wire connector. So if you have trailers with both plug types this will work.
