I purchased #1 new. When I salvaged it, I found the rearview mirror was tied into the harness beside the driver’s left foot. Remove the cover and you will find this plug. The wire is brown with a red stripe. The wire goes up the A pillar, across the top of the windshield to the center console. There is a small black plastic piece that covers the wire from the upper console to the mirror for looks. I have installed a mirror in #3 & #4, so it works.
