Are you sure it's an 88 harness?? I've seen newer 91-93 harnesses with 1 plug like you stated.

it came out of a 88 gt convert but alot of things on the car were weird..the car was an abortion job so i stripped it and junked it..im thinking the harness came from a lincoln or f-150??thier is also a low fuel light relay box on it???

Up to the 1986 model year, mustangs had a low fuel light warning module, but it was in the dash harness. It could possibly be out of an 86GT. I know the harnesses changed a couple of times over the years. I recently did an EFI swap into my 84 GT and found through wiring diagram research there were differences in wire colors and connector locations.
