Does anyone know what wire i hook the guage up to on my o2? i have 2 black wires, a white wire, and a green wire...

 

unless that's a wideband o2, the guage won't help.

 

white wire

 

witch brand of gauge do you have?

actually i was talking about just running straight to the o2 sensor, but yeh your better off running it to the ecu.

 

why????

the + and - can be take off the under dash fuse box and the signal wire's go to the ecu mutch better install to me

 

If it were me, i would put the + on any hot ignition switched wire, the - on any ground, and the signal wire on a wideband o2. It doesn't matter where the guage gets power from, just the signal. And the signal from a stock o2 is completely worthless as far as a guage is concerned.
