Thanks for the info, and the link to thread. The last poster used #38 for constant power, which is reachable through the door, so I'll try that if I get to that point.
I don't understand why they couldn't make access to the entire fuse panel easier, so to replace some of the fuses around edges, you have to take out the glovebox
. Much easier on wife's Audi which I've already hardwired one.
