Auto dimming mirror is always dark even with the connector disconnected. I assume the fluid has leaked from the mirror to cause that. I've also noticed the mirror has the keyless entry receiver integrated so I'll need to keep the mirror. If I get a replacement mirror, do I need to reprogram my keys?

I'm thinking of going with an aftermarket mirror that attaches to the stock mirror so I can add backup camera and a compass. Anyone have the pinout of the connector so I can tap power?
