on a 2000 si what color is what on the o2 sensor
white-signal
green-ground
blacks(2)-heater

 

white = o2 sensor signal
green = pos. for o2 sensor heater
blacks = neg.'s for o2 sensor signal and o2 sensor heater

 

I have a question about this too. 95 Civic, what color do I splice for the A/F guage

 

SPLICE THE BLACK ONES, CAUSE THEY GIVE SIGNAL.

just think about it man. what does the o2 gauge need? an o2 signal. does it not follow logic that the o2 sensor gives a signal on the o2 signal wire? perhaps THAT is the one you need to tap! the WHITE ONE WOOHOOO.

 

I didnt need a wise *** reply, I have it spliced into the white one. I just wanted to check and see if I had it right.

 

tap into wire D14 at the ecu, very simple.

 

sorry, my wiseassness is a byproduct of society, I can't take the blame.

 

which means he's to sorry to admit he can be a ------- at times!!!!!!!!.

I'm a -------!!!!!!!!!!!!!
