I have a 1975 Johnson 75 HP Sea Horse. The tilt/trim has 3 wires Red, Blue and Black. The switch has 5 wires. 3 are hooked up, 2 are not. One is black striped the other is white striped. When I hook the white striped wire to the blue striped raise or lower the unit the needle moves up and down, but not the correct position. There is a solenoid with the red, blue and black hooked up to the battery. I cannot figure out how to hook up the switch and guage.
