alpha I Gen II 2003 twin 4.3 Ok... I installed new trim limit sensors- on both drives -adjusted the starboard side and everything went perfect -go and adjust the port side and everything goes perfect -hit the trailer up switch and only the starboard side goes up -I have looked at the wiring diagram for the two drive system but I have three wires like the single system shows any suggestions -and no I do not know if the trailer switch worked before I installed the new sensors -they were by passed as they went bad by the po
Thanks
