you will not like it

EGR valve fouls the fuel rail so I have to swap it for another.

How do I hook up that extra wire from the wide band O2 sensor?,


the EGR valve does not and can not "fouls the fuel rail "
so kindly add great detail to what it is that you are attempting to state .

and

you will need to use a 4 wire 02 sensor that was designed for your system , your ECM and harness can NOT be retrofitted to use

an AFR sensor .

5 wire sensors are NOT 02 sensors they are Air Fuel Ratio Sensors , they do not and can not interchange
