Default 89-90 Legacy EDM headlight leveler wiring diagram

I got a set of LHD EDM lights for my legacy. They have the electronic levelers on them. I know I can use the lights without having the electronic levelers hooked up, but I'd like to use them if I can.

I was sent a wiring diagram, but it does not match the connectors I have. I'm assuming it's for the EDM 91-93 Legacies, rather then the EDM 89-90 MY's.

If anyone knows someone in Europe, or could help me out, I'd greatly appreciate it.

Here is the incorrect leveler wiring diagram.

Here are pictures of the connectors on the motors & the switch

As you can see, the connector in the diagram only has three pins. Mine have six. Also the switch in the diagram has six pins, my switch has seven.

Just a little update.

I've done a little homework, and found out that the sti levelers for the WRX are similar but not quite the same.

These two threads on scoobymods go into details how they work.


My switch has an illumination ref source, and a ground for that.

It then takes a 12v switched source and feeds that to the levelers via the switching knob.

The levelers have six inputs. One is 12v power lead (most likely source power for the motor), ground, and the four positioner inputs from the switch. The signal from these leads probably act more or less like the trigger leads for a relay.

I've taken a few pictures of the switch, connector, and labeled them.

I plan on testing the leveler motors this weekend to verify exactly which pins are which. I'll take pictures and label them like I did these, and draw up a wiring diagram for others.
