O2 sensor wire colors?

[screaming4snow]

What color is the sending wire? there are 4 different colors coming out of them. im tryin to hook up an air fuel gauge i got from the rents for x-mas haha. and also for installing a voltmeter what should i hook that up to?

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.

i think its black. white. white with a black line. and a green.

Regardless, it's the solid white.

as for the 12v source on pin 16, thats a constant 12v? when hooking up volt meter thats goin in my pod is that still the one i would want?

[iminhell]

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
