Wiring diagram. Looks like both of those wires are hot either in the up or down mode. [Only 12vdc to one wire at a time.[NOT BOTH AT SAME TIME] Then the black is ground. Maurice
In other words according to the diagram
Battery to red gets the top to go up
Battery to yellow get the top to go down
Black stays attached to body all the time.
Hope that is clear if not just ask. Maurice
