I'd like to tap the 12v from an OBD2 connector -- while there's something else plugged in. I want to use the power for my battery/charger monitor because it's about the only unswitched 12 v easily accessible in today's vehicles.
Googling about, I found lots of splitters (to kludgy), power only taps, and OBD2 breakouts ( no real help). I really just want something like a male/fermale connector with the 12 v and ground prought out on a pigtail or similar.
Bonus points -- my monitor is avr powered :).
Appreciate any suggestions,
