Switched the S1& the S2 wires now i have reverse but no foward. I'm going to remove and recheck the F/R switch. So far I've changed the ignition switch, controller, and the F/R switch. The reverse buzzer on the diagram is connected to a M4 switch that's connected to a separate pos and neg connection. I have a M2. So I'm thinking on leaving it disconnect. All wires are connected as per the diagram. Any suggestions?
