Yeah mine is ignition on. Honestly I don't really like that because I always turn my truck off and then I'm like dang, I wanted to open the garage door. My garage is separate from my home.When you did this is the homelink on ignition and the vanity light is constant? I assume you just followed the infotainment instructions? I bought the same harness.
I don't want the homelink to be constant so people could break into my car and open my garage while parked outside.
I saw your post about getting hot to the passenger mirror, you'd just need a two conductor wire and just tie it in with the driver side. Maybe @Jimmy07 could make you one. I do remember fishing that cable to the mirror from the overhead console tried my patience though.
