I'm putting a T-bird wiring harness in my mustang! Its a 4 cyl to 5.0 swap. I already had the t-bird so I'm just swapping everything over into my 88 mustang. The t-bird is also an 88 speed density car. But anyway There are like 2 plugs on the harness next to the computer (only one left in the stang from 4 cyl) What do I do about these and what do they go to, and what about the plug in the car? Thanx in advance -Tony

Here are the plugs. The round one is in the t-bird harness and the green one is part of the car. There was another one that plugged into some kinda switch, relay, or something under the dash in the t-bird so i just stole it. But i hope these pictures help cause i need to figure this out. Thanx!!

Yes the green one is part of the car, so does the 5.0 mustang harness have the plug to mate up to this. I also would like to know what the round one in the t-bird harness is for. Thanks

yes the mustang harness has the green plug to mate up with the green plug on the mustang body harness the grey plug i havnt figured out what its for yet i just did a 4cyl-5.0 swap in my 90 coupe i bought a mass air harness out of a 93 gt and that harness has both the green and grey plugs on it but my body harness only had the green plug im thinking because of it being a 4cyl harness thats why it doesnt have the grey plug Im currently making a book on doing this swap so im doing alot of research and if i come across what this plugs for ill be sure to let you know if you get a chance check out the website www.fordfuelinjection.com theres alot of good information on it

I have the feeling the green plug in the car may go to my gauges or something maybe IDK. But the t-bird had digital gauges so that may be where i run into an issue but I guess I'll put he car back on the back-burner and hunt for a mustang wiring harness. Thanks guys. This sucks!!

the green and grey plugs go from the harness to the body plugs. they are on the passenger side down near the factory ECM. hope this helps.

i just saw them on my car. and remembered this thread.

well i just found out the gray plug goes to my ffuel pump. I'm going to try to rewire it to the relay if possible if not i may just rewire it all the way to the pump. Is there any wires in the green connector that are a must have? Gauges etc.. Thanks -Tony
