Awesome, thanks! Time to patch mine up

I'll go ahead and probe the cars end of the wires tomorrow to document exactly what they are.

So could We just fix it with this harness?
3pin/10pm in housing version?

That might be the best approach. I just took mine apart and it's not easy to patch because of the small size of the harness, and the fact you'd have to have the right wire pin to attach to a 4th wire and connect in.

I got a part number off of it but I couldn't find anything online: 625-1943-000

Thanks! With the proper pin out at both sides we can just order the correct adapter from a 3rd party vendor then!

Here's the wiring harness from the mirror I ordered in anticipation of my GR arriving. Hard to make out in this picture but the blue wire is present on the black plug end. The harness was made on 12/15/21.

What’s the full part number?

901-1387-000 for the harness.

H501SCC000 for the mirror.

AECHL5 is the model stamped on the mirror housing if anyone wants to compare.

I ordered from
SubaruPartsForYou[dot]com. Shipped super fast.

Like @emce said no dice on that harness part number.

I’d much rather swap this out myself, don’t really want the dealer to have to deal with my dash cam and then have to worry about them scratching my clear UV/IR tint on the windshield.

The red and blue wire are tied together in the jumper lead. The red wire is switched 12V, the brown wire is ground and I'm not sure what the yellow wire is. I can't get 12V on it at all, and I get no meaningful measurement with my meter set to mV either.

If you shine a flashlight at the glass just right, it looks like there might be a screen in the center.

3 wires bad.. 4 wires good. Not super complicated. I have been nowhere near my car to take a picture. Congrats on getting your mirror all squared up.

I thought you were very clear!

Except that the mirror itself has more than 4 wires available, so anybody wanting to bench test it has to guess instead of knowing which wires to go to. He was not helpful at all.

I ended up buying a harness from Bob's Mirrors. Got it plugged in this evening and homelink finally works!
