Added Homelink to my 2017 Tahoe LS with mods.

[Ryan212]

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.

You said that you found it in gray but, in the pic, it looks tan. Did you paint it? And, if so, with what? (Just curious). Looks good.

Its gray and matches the factory color, My garage door must be causing it to look tan in the picture as the sun was reflecting off of it.

I just bought an 18 ls can’t belive it doesn’t have homelink so I am trying to add. Was the harness already there to plug the homelink in to? If you don’t change the pi out as you did?

 

[Ryan212]

The original console harness does not have homelink provisions, but the roof harness is setup to accept a console harness with homelink. The upper console I purchased had a new harness and the entire homelink assembly. You can simply swap out the entire roof assembly. (cheaper) or purchase the homelink, buttons filler plate and harness.

Awesome! Thanks for the write-up!

Are you referring to Pin #17 and 23 in the BCM?

I installed a homelink console in my 18 the homelink lights all light up but I can not get them to program to any of my doors? The home link on everything else I have ever had works perfect.

Sorry, just saw this, Those numbers are for the upper console to body harness terminal locations. It is a large connector.
