Heyguys, I have successfully installed heated mirrors on my 2009 "Z". it's not an easy task. I also bought from ebay nissan altima door harnesses from a 2009 nissan altima. With both harnesses I had enough contacts and wires to do the job.1: bought mirrors from Courtesy Nissan, they are actually cheaper that the non-heated. 2: Got the wiring diagrams for heated mirror "Z" 2011. 3: Removed mirror & replaced mirror and soldered connections on mirros and pined them into the connector. 4: I removed both door panels and wired the door from the morror connector to the door main connector. This is a little hard to run the new wires through the conduit. 5: The ground wires on the car side are there already so you have to splice the ground mirror into the existing ground wire. The groung pin on the left kick panel is # 13 on connector M5 / D1 on the right kick panel is # 14 on connector M124 / D31. This is the easy part if you have the right type of pins, this is the key note.
6: The power wire for the left mirror is not there so you have to run a wire from pin # 10c on connector M3 to pin # 44 on connector M5. Then forthe right morror it is totally different. The wire 9C is there but is only connected for the heat contoller not the mirror. So I spliced in the power wire behind the switch for the defogger switch and ran it to the right kick panel pin # 44 on connector M124. 7: Installed fuse # 13 in the fuse box and powered up the defogger switch and with a multimeter I checked for power and all worked as advertised. I used those stick on thermometer and placed them on the glass and the pemperatures climbed. It all works great but it was a pain in the butt and really not worthit. I'm an aircraft avionic technician and for me it was not really that easy but I enjoyed doing it. Just remember that if you decide to venture in this direction the correct pins is the key factor, you will need both male and female contacts. Good luck. Make sure you follow the wiring diagram.
