86 was a mid-year change. California cars got a mass-airflow sensor based EFI system in mustangs, and the rest of the country still had the speed-density EFI system. 1987 went MAF nationwide. As for all 5.0s, no. You would need a thunderbird harness for a thunderbird. You might be able to lengthen some wires from a mustang harness, however.
are all 86 ford 5.0.s the same?and are the engine harnesses the same?
