[QUOTE="Hole Shot, post: 758326, member: 12894"] I still haven't had time to look at the voltage. But the ECM uses 5v as a reference voltage. So I'm Assuming this runs through the ECM or trans controller or both. A diode doesn't drop voltage unless you are using it in a ac system. A diode will stop all voltage in one direction and let voltage in flow freely in the other direction. So if you put a diode in each of the power wires that would stop you from stray voltage going down the other positive power line and causing a problem. But you still have a issue if you turn both power sources on at the same time and doubling the voltage at the actuator. Understand? Sent from my iPhone using Tapatalk [/QUOTE]
