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?
