I purchased an air fuel gauge and instructions say to connect to oxygen sensor signal wire. I have a '91 5.0 and need to know which of these wires is the signal wire :
Right Side
gray & blue stripe
gray & yellow stripe
black & white stripe
Left Side
gray&yellow stripe
black&white stripe
red&blue stripe

Thanks,
Troy

Splice in at pin #29 at the computer it is a DG/P
wire. Mine works fine in that location.
