Thanks for the quick reply! Since today was the maiden voyage for Black Beast II and it popped a MAP pressure code like my first SRT-6 used to do from time to time, I erased the code and disconnected the battery for a reset. I will clean the MAF sensor tomorrow and that problem should stay gone for at least 6 months.
Low and behold after that reset, now my dome light goes on when I hit the unlock button on the fob and goes off when I turn the key in the ignition. I'm glad I don't have to mess with that pump thingie!
