I just installed the a/f guage in my talon and for some reason its jus got one green light lit. I installed it on the white wire coming out of the ecu (it was the big plug, top row, 4th from left).. I hooked it up just like I printed off one of the sites I came across. Any idea why its not working right? I got my power from the fuse box and grounded to a screw in the Dash. My only thought it that the pic I used show tapping power and ground from the writes outta the ecu. Any suggestions?

 

Aren't the white wires on the O2 circuit the power wire for the heater assembly? The O2 signal wires are normaly purple or blue I think.

 

what he said. it should be a blue wire if im not mistaken

 

found different source thanks
