Homelink Installation on 2014 Suburban

[teddyv2]

I posted this earlier, but in the wrong forum. There are allot of guys trying to figure out Homelink wiring in the roof console's of their trucks, so maybe this might answer some of their questions rather than cut into their wiring harnesses.

 

I just traded my 2000 on a 2014 Suburban LT 1500 (previously an Enterprise rental) and didn't realize there was no Homelink in the roof console. My foolish mistake. So I picked up a Homelink on the net ... checked it and it works fine. In the console there are screw stands and mount to fit the Homelink transmitter and I can fit the buttons through the console facia, but I have one problem … the loom feed wiring.

A Homelink has simple connections … a 12v, ground and lighting. I would simply wire it up, but the 2014 has so many damned computers in it, I'm worried about splicing into monitored circuits.

I checked Chevrolet parts and they have no kit pigtail to retrofit a homelink. The female loom feed wiring to the roof console has all pin feeds wired, but the male connector has unused pin locations and I'm thinking these empty pin locations have a dedication for the Homelink, but which ones?

Does anyone have a diagram to the 2014 Suburban roof console wire loom that designates pin connections?
