Can anyone help me in connecting these wires of the auto-dimming mirror harness to the wires under the overhead console? I have a 2000 Lexus RX300 that didn't come with an auto-dimming mirror. Thanks for your help.

Interesting .. I had not heard of RX without auto-dim.
Early year models did not even have memory (motorized) rear-view mirror.
There are some with compass built in.
Depending on what you are trying to retrofit, you need Ground, +12v.
Newer mirror has the night and the light (facing the front of the vehicle detector and another that senses light from vehicles behind you (non reflective oval at the middle bottom of the glass). The mirror then sends out signal to the side mirrors and all three [2 sides and 1 middle] all dim. The mirror also has a +12v line switch do enable or disable the dimming feature and a small green LED to show its on/off status.
I would NOT know which wires you tap into the harness. Hopefully the above explains what wires come out of the mirror.

The wire harness that was cut was the harness from a salvaged RX300. The mirror I took off has the harness wired to it and is not cut. What I need to know is which wires on the RX300 do the 4 cut harness wires need to connect to. I'm guessing White/Black to White/Black, Red/Black to Red/Black, Green/Yellow to Green/Yellow. However where does the Green/Black go to??? Any help would be greatly appreciated. Thanks.
