Air/Fuel ration guage install
 

Need a little help on my guage install. The guage has 3 wires. Hot, Ground, and one that goes to the O2 sensor. Got the hot and the ground covered. Just need to know which wire on the o2 sensor is the one I need to tie into. Anybody got a good guess?

when I did mine, I got the wire colors from a ford tech guy and he gave me the wrong colors, so I followed the oxygen sensor harness to where it plugs in right under the mass air meter.

the right one was a red wire and the other one waswhite/grey.
I would suggest following the harness.

I also wired a switch to switch sides.
I can look at the right side and the left side.
