The 5.0 Mustang engine mounted fuel injector harness was the same from 87-93.

I think there was a additional harness that plugged into the "salt and pepper shakers" as a "fix" on one of the years... Im not sure tho.
 
i can't find where i found that there are three different harnesses the engine harness is from a 93 5.0 that i got from a friend that's going carb.i am not sure if i got the fuel harness as well but hopefully won't be a problem.

thanks for the info i will look at the wires to see if they match
 
What I am thinking of was an extra set of salt and pepper shakers like a extra add on.....I may be wrong.

My current 5.0 has those. It was supposed to be a fix for engine motion causing strain and intermittent connection in the 10 pin connectors. For most owners, it seems that it causes more problems than it fixes.
