Unless I am mistaken, my new mirror which I looked up under Mito Corp a distributor for Gentex ID's my mirror as a Genk21. The plug in the back has 14 pins with 5 wires, Blk, Yel, Grn, Grn/Blk, Grey. I took the Yel for power and spliced it into the original harness for pin #1 and Blk for pin #2 I believe the Grey and Grn/Blk is for the temp sensor. Once I get it installed I will cut off the original plug and just use the one which came with the new mirror. By the way this is a used mirror which came off a 2004 Saturn for $30.00
