Hello all this is my first post and I wanted to share with you some tech info I learned while trying to add a Mopar sunvisor with homelink. First off, I have a JLU sport with lighted vanity mirrors. After looking at pictures I determined that both my visors and the Homelink visor had the same three wire connector. My stock visors only used two wires but there were three going into the connector on the vehicle side. I sourced a visor from a junkyard for only $60, plugged it in, and nothing.... After researching and studying electrical diagrams I found that the gray homelink power wire is fed directly from the BCM so without a reflash there was no power coming through that wire even with the engine running. I have the aux switch group from the factory so that made the next steps easier. I went into the passenger kick panel and unpinned the gray homelink power wire from the BCM connector, then wired up a pin from an old connector I had to the ignition switched wire under the passenger dash that came with the power group and connected the two together. I could have easily just cut the wire and spliced it directly to the power but this extra step allows me to re-insert the pin in to the BCM connector and return everything to stock if need be. After wiring everything up the Homelink buttons light up when I turn the ignition on. I could have easily spliced into the power for the LED vanity lights but I like the idea of the homelink being disabled with the ignition off. So there you have it. It is fairly easy to add factory Homelink to your JL, but it is more than just plug and play.
