2018 Silverado 2500hd homelink mod

Jrs 94 · December 13, 2018

Just did the same swap, that plug supplies power to the relay mounted to the console for adding a light bar. Did your original have a long thin switch in the center that did nothing? Mine did. My truck has the plow option which included provision for the light bar. Could be good if you wanted a big led bar on the roof I guess. Anyway, Everything works. My homelink console is a 2017. Glasses box is lots smaller. Crazy that homelink isn't included for what these trucks cost. Hope this helps.

Hello everyone. I just recently purchased a 2014 Silverado and i'm looking to do this conversation soon. I just wanted to say that this thread was very helpful with all the in-depth chat and part numbers.

Thank you all very much and I'm looking forward to joining the Group.

Jrs, how did you add your homelink? I have a 2019 2500HD with the plow prep package so I have the switch for adding a light bar. I want to add homelink to my truck but I need that switch in the middle for my light bar.

I found a whole new upper console on eBay with homelink in it. This one has a switch for rear sliding glass window, not for the light bar. It was just a plug and play swap out. Took about 15 minutes. I also had the plow option but don’t plan to use it. You will have to be creative to keep the light bar config, unless you can find one with that setup on eBay. GM was no help. Be careful if you do the swap. The 2017 glasses bin is lots smaller than the 2018. I did a return and swap to get the 2018 bin. No idea if its the same on the newer trucks. Good luck

I have on of this for sale, if interested. Harness will need to be replaced to get power to it since it’s all it need to work.

swap out was flawless. this part is all that I needed for mine to function perfectly with the existing over head harness.

I have searched and seen the part required for my 2018 Silverado was discontinued. I have been order parts to add to my existing overhead consol...

Maybe someone can chime in...

So as far as I know it all I need to install OEM Homelink in my 2018 Silverado LT is the following:

Trim plate (84435116)

Homelink Transmitter (84084118)

Transmitter came with a short 4” long pigtail

Transmitter buttons (22834550)

Can anyone confirm my assumptions?
