Hey guys,

I just recently put in an ATI procharger and some autometer gauges. Boost and A/F ratio. I was able to wire up everything except for one wire. I can't find where to hook up the signal wire for the A/F ratio gauge. I found the O2 sensor but the wire disappear somewhere in the engine compartment and I cant track them inside the cab. Any help would be appreciated.

 

If you are trying to feed off the O2 sensor you will never find any of its wire in the cab. The sensor wires remain outside of the cab.

let me clarify. After reading some more...I am looking for the signal wire from the connector to the PCM. Is there an easier place to find this wire?

 

I will need to know which truck and year.

It is a 2003 supercab F150 XLT 4x4 with the 5.4L.

thanks for helping
