For the O2, white ... both blacks are grounds and the grey is the +12 to the heater.
For the Voltage gauge, tap into pin #16 of the OBDII port. It's the bottom and furthest to the passenger side. That way you don't have to worry about running any wiring to the engine bay and it's a very short run of wire.

It is a switched 12 I believe, which is what you want.
Constant 12 would drain the battery as it sits, meaning the gauge would always be on.

yes im saying that pin 16 is a constant 12v. so im trying to figure out which pin/wire would be on a "switch" so it only turns on when the car is on
