That was a piece of cake once I called the guy who works for Gentex and got the correct pin outs for the wiring. I ran the temperature sensor probe wires thru a rubber gromet that is barely visible from inside the car to the underhood. The gromet is on the right side of the firewall below the ECM.You will have to remove the kick panel moulding,the right underdash sound insulator moulding and I took both of the windshield "A" pillar garnish mouldings off to route the wires. I ran the temp sensor wires from the sensor (that I mounted inside of the right grill air intake behind the grill on the metal bumper support)up the "A" pillar ,under the headliner to the original mirror connector and installed the terminals in terminal cavities 4&5. I ran a 12v ignition feed wire from the gauges 10amp fuse to terminal #1 or the mirror connector and up the left side "A" pillar and under the headliner. Terminal cavity #3 is used for reverse(so that the mirror,if dimmed and the car is in reverse will brighten).I chose not to bother adding that circuit. The other wires in the original connector will remain in their original locations.The mirror works great! Here are some pictures of the install!
