ReplacementCorp, one of the largest factory electronics websites, has branched out!! If you?ve been to our site, you know we have a HUGE selection of OEM parts and compatible accessories. Now we?re offering a few select products here too. Same great ReplacementCorp quality.....in a new location. SUMMARY OEM GM part Part number is unknown For use with select HomeLink transmitters Guaranteed for part # 22809886 84084118 Because that's what this was paired with We removed it to sell separately Has never been installed in a vehicle Removed from an assembly line leftover console Comes exactly as pictured Has spaces for 4 pins But only 3 are populated For replacement use only We cannot provide assistance on upgrades Works for part numbers 22809886 and 84084118 No others are guaranteed DETAILS This is an original Homelink garage door opener transmitter connection cable for select GM vehicles. The Home Link transmitter module it was paired with was part number 22809886 or 84084118. It is not included. Just the harness pictured. We have another listing in our store that includes the transmitter. We obviously cannot guarantee it with any other part number not listed. It will come exactly as pictured. It was removed from an assembly line leftover console, so it has never been in a vehicle. It has spaces for 4 pins but only 3 of them are populated. If you are purchasing this to upgrade your vehicle, you should expect to do a little work. The intent of our ad is clearly for replacement. We're not a custom shop or an install shop, so we can't tell you what you'll need to do to make it work for you if you don't have HomeLink now. (Or if you do have HomeLink, but the transmitter is not part number 22809886 or 84084118.) If other parts are required for use of this piece, you will need to obtain them. You should have this planned out in advance. We do not guarantee it will work for you simply because your year and model is listed. The application list is merely a starting point. APPLICATIONS We do not guarantee it will work for you simply because your year and model is listed. The application list is merely a starting point. This works with HomeLink modules with part number 28809886 or 84084118, so make sure that's what you've got in your vehicle. We're not selling this for upgrades. Just replacement.
