I am keeping my eye on this install... My mirror is de-laminating as well, and are in need of a new one. If I can get rid of the garage door opener on the sunvisor that would a huge benefit.
Wiring should be easy. It's 5 wires.
-Ignition on hot
-Constant power hot
I'll ground it on the dome light ground wire, and then run the two power wires down to the fuse box area and find appropriate wires. Really hardest part is running the two wires to the front grill area to mount the temp sensor. As soon as I get my wire in and make a harness i'll get this done
