Which wire do I hook it up too?There are 3 wires 2 white and one black Im pretty sure it goes to the black one. Does the car need to be warmed up for the gauge to work? That is what i was told and just wanted to make sure thanks for the help.
Hey Hissin50. Can you explaing how to set that one up? do you just have to run wires to both o2 sensors and then to the wire the toggle inline to the gauge. I'd like to do that rather than using 2 gauges to measure the same thing. A more detailed explanation of the wiring would be sweet if you or anyone else could provide it.
first buy yourself a 2 position toggle switch.. not just off and On..
you are looking for ON-OFF-ON.
next run 2 wires (one from each sensors( black one)) to each side of the switch
o2 G 02

G would be wired to the gauge... now car needs to be running for the guage to work.. i'm assuming it's an autometer a/f gauge.
so it's not gonna do much until the 02's heat up, even then it's gonna be a light display until you are at WOT.
click the switch to either side to see the reading of the other sensor.
