Home Link rear view mirror

Of course you can. I just finished replacing mine. it works great. the constant hot wire I used in to the passenger's vanity light. the ground was in the overhead console. I had to run a wire across the headliner (tucked inside next to the windshield). and then behind the head airbag, down the pillar and into the bottom of the dash. The flesh colored wire in the ECU harness is a good switched power wire to connect to. Do yourself a favor, if you have a soldering iron make the connection that way. The 18ga wires are too small for the t-tap connectors.

Pretty simple, actually.
