hi everyone i just got a air/fuel gauge and i was wondering what color the signal wire comming off the o2 sensor... thanks

 

Ummm....You talking about the wire at the O2 sensor? Youve lost me...

 

Pin 2D at the ECU, grey wire. Stay away from the sensor's wire.

 

i just got one too and was curious to which wire to hook it up to. in the manual it says to hook it up to the ECU and the O2 wire. which one is it? just the grey one?

 

hmm.. i bought an 02 sensor last year, had it in my coat pocket for the entire year. When I finaly get downtime and unscrew the old 02 sensor... I can't find the new one. Talk about frustrating. Oh well.

anyhow, I'd pull the wire at the ecu, not the enginebay. unless you're like me and have a mess of wires running everywhere already because you expect a haltech within 12 months. *shrug*

My engine bay has 6 relays + the stock relays

 

ok so where can i get a pinout map of the ecu or can you explain it to me.
thanx
