hey, does anyone know about my 2003 prestige trailer? I just got the boat and trailer and i want to tow it with My 97 Tahoe. I just have the four wire flat connector and the trailer has the five. I know the fifth wire activates the release solenoid when backing. the trailer has a manual release on the toungue, my question is will the surge brakes still work otherwise, i.e. traveling down the road, without the fifth wire? thanks for any help
