Prodrive 4 Pin Switch! - Subaru Enthusiasts Car Club of the Sierras

So it's look like this is it?
Of course he does not have solid knowledge on the what the pins do but I think we can figure it out?

I have successfully installed the level switch on my uk300's. The following explaination is for the connection of the 4 or 6 pin level switch to a 3 wire level system (EURO spec).

All you need is the switch. There are three wires on the headlight level motor.

Black = Ground
White/Red = +12V
I spliced into the headlamp wires to get power and ground.

The third wire is the level wire. You need to pull this connection to ground through a resistor to get the headlights to adjust up and down. If you have the 4 wire Euro switch all you need to do is connect the RED level wire from the headlights to the switch. The 4 connector switch has:

(cant remember exact pinout, for explaination purposes only)
1 - Power
2 - Ground (Power and ground are used to illuminate the switch)
3 - In/Out signal
4 - In/Out signal

If you measure the resistance across 3 and 4 while you change the switch position you will notice the resistance change. Hook the RED level wire from the headlight to pin 3 or 4 on the switch. Then connect the other pin to ground. This will pull the level wire (RED) to ground through the resistor.

Good work Tyson! That looks like enough for us to get it working. We were actually on the right track Saturday... a few hours of screwing with it, I think we'd have figured it out.... but it's much better to have a schematic instead of just winging it.

ok, so then I take it they're not in

but you know how to put them in

and that's 99% of the job

good luck with the install

just dont blind me
