Headlight Leveling Motor / switch Wiring

Hi, I come around with another mod attempt. Does anyone know what are the 3 wires/pins of the headlight leveling motor and the 5 wires/pins of the switch on the dash? 

I'll attach an image for a better understanding of what I mean 
 

 

 

The leveller is a servo, and moves until the voltage on the control pin is equal to the voltage it gets from a potentiometer connected to the output gear.

The switch just selects a voltage tap from that chain of internal resistors to feed to the control pin.

You could control it with a continuously variable potentiometer if you wanted.


After many years the potentiometer inside the servo either gets dirty or wears a hole in the track and the servo starts to buzz as it is continually moving very slightly trying to match the voltages.

So far I know some stuff

1 - connects to the leveling switch
2 - 12V +
3 - GND

leveling switch
judging by the diagram above

two pins of the switch are intended to go to either leveling motor exactly which of the 5 are, can't tell.
the switch has to get some input from the parking lights or something for the switch to show the orange light. so that's another pin

that leaves me with 2 more pins I suspect one of them gotta be a GND too but I'm not sure any help?

Can you read a wiring diagram? Do you have a multi-tester and know how to use it?

Assuming the switch matches the one in the diagram, determining which pins are which is a matter of simple resistive tests.

turn the knob to p3 - look for two pins with a dead short between them, those will be pins #4 & #5.

turn the knob to p0 - look for a pin with a dead short to either #4 or #5 that will be pin #3.

look for a pin with some amount of resistance between it & #3, that will be pin #6, confirm by measuring the resistance between #6 & either #4 or #5, the resistance should change as the knob is rotated.

thanks for the reply, yeah right now I don't have the switch with me, waiting for it to arrive. I'm trying to get some knowledge in advance

I will try what you suggested
