goofy interior light behavior

Known issue on the cars radio wiring is that switched power and constant power (memory) is opposite of the wiring diagram. Using the Metra harness will connect as per the wiring diagram, hence your switched and constant power are reversed.
I’ve experienced this issue first hand.

Brilliant. Thanks for the insight on the 12v lines being swapped. I'll get in there with a voltmeter and verify (which I should have done on the install) and swap the connector positions.
