I am trying to figure out what the single orange wire and plug on an engine harness I have is for. My 94 does not have. It is on the firewall end of the harness with the four block connectors that sit behind the fuel filter. Please see photo
Or for what year or engine code it fits F, S etc....
Correction on this.......it is a brown wire that only has continuity to the upper right pin in the pic. The other harness has a plug in that spot.........
