Hi all,
I'm trying to add a USB port near the rearview mirror in my 2010 Vibe for use with a dashcam. I'm currently running an unsightly wire down to the lighter plug to power the dashcam, which I would like to get rid of.
I made the incorrect assumption that the Onstar mirror would have an ignition 12V line in the 16 pin connector, which it does not. There's one wire (pin 10) that has a 9.8V output, but it's insufficient voltage to run the 12V-to-5V USB buck converter I bought. The closest 12V that I can grab would be the one that powers the map lights, but it appears to be always on, so that's a no-go. :/
I'm concerned about running an ignition 12V line from the fusebox through the A-pillar, because I don't want to get lashed in the face by wire should the A-pillar airbag ever go off.
Looking for suggestions/recommendations...
