hey ford folk - have any of you installed an AutoMeter Air/Fuel ratio gauge? I mounted a transmission and air/fuel ratio gauge in the my '02 F150 SuperCrew - but have had no success with the A/F Ratio gauge hook-up - What wire do I use for the A/F Ratio gauge - the directions indicate the source wire between the O2 connector and the control module?!?>!? Does anybody know what wire they are speaking of? Where can I find it? Is there a wiring harness I should be looking for?

Thanks in advance for the help!!!
