Finally got around to converting both my front power points to switched using N/O relays. I have learned two lessons:
1. Don't work on anything plastic when it's 26* out. The shifter surround, which normally just pulls right off, shattered into 3 pieces. Ostensibly they still make them, so maybe it's a $40 mistake rather than an irreparable one. For now it's epoxied.
2. If anyone ever needs a switched power trigger and is also not a fan (or just out of) scotchloks or fuse taps, a/o 2010 switched power to the rear wipers is the Green/Blue wire at pin 5 in C219, which is the white plug in the driver's kick panel. If you don't have rear wipers, the wire terminates there, and you can depin and use it for whatever. If you are fuse-tapping, it's on 20A fuse# 180, shared with the front wipers.
EDIT: Another 2010 popped up at the super-close, super-busy junkyard on the 17th. Grabbed the shifter surround for $5, plus some other trim I needed. When I have time, gonna make another trip with tools to grab the intact upper B-pillar trim, since mine had the back cut off when the cargo partition was installed.
