I've always had homelink on my previous vehicles, but the 2017 Tahoe LS I just purchased did not have it.
Ebay to the rescue, new OEM console from a 2015-2017 Tahoe/Suburban in gray 84187049
This was cheaper than buying the harness and Homelink transmitter and buttons together.
Then due to my LS not having a power lift gate. (the tahoe options with Homelink have the selector for the lift gate height)
I replaced the cover plate with one from a Silverado.
Silverado trim plate, gray, homelink and dome switch, no power slider or sunroof. 23104432
For security reasons, since I sometimes park outside, I want the garage door to not work without the key being in the on position. This required changing the power source for the Homelink.
I also wanted to remove the extra wires, I unwrapped the harness to follow the Homelink power wire. It went to pin #17 which is battery positive voltage. I removed the extra wires from the harness for the lift gate switch. Using a needle, I removed the 2 pins from the electrical connector, and cut the 2 splices.
I used one of the extra pins that were removed to now power the Homelink with pin #23 as it was unused. After changing this wire, I wrapped the harness with the factory style cloth tape and reinstalled it to the new overhead console. It looks factory as expected.
