I'd do the mass air conversion. My car came with the stuff to do it from the previous owner include the ford motorsports computer adapter which is really hard to find. The throttle response is 10x better. It doesnt even feel like the same car. Some people say you'll loose power, but even using the stock 55mm meter cars seems to run so much better than it did. Gonna try to souce a 70mm from a junkyard hear soon.
94-95 Mustang GT MAF - $40-$100. It is 70 MM instead of the stock 55 MM on regular stangs built prior to 94. It uses a slip on duct on
the side that goes to the throttle body and a 4 bolt flange on the other. You need a flange adapter to fit the stock slip on air ducting
that goes to the air box. Wiring plugs right in with no changes. *1 *2
*1.) Metal flange adapter Kurtz Kustomz Motorsports, Inc. KKM Buy the TR70 for $44.95.
Or spend some time on eBay looking for one that may fit.
Try AutoZone and ask for 81413 - Spectre / 3 in. Aluminum Intake Mass Air Flow Sensor Adapter at $12.00. You may have to order it online.
*2.) MAF & sensor interchange
The 94-95 Mustang 5.0 MAF & sensor is also found on:
1994-95 Mustang 3.8L F2VF-12B579-A2A,
1992-94 Crown Victoria 4.6L F2VF-12B579-A2A,
1994-95 Mustang, Mustang Cobra 5.0L F2VF-12B579-A2A,
1992-94 Town Car 4.6L F2VF-12B579-A2A,
1992-94 Grand Marquis 4.6L F2VF-12B579-A2A,
Evidently the –A1A, -A2A, AA, etc. on the end of the part number is a minor variant that did not change the operating specs.
You should be able to ignore it and have everything work good.
just cuz im lazy but whats the link?and i got a question for you guys does this look the same as a stang this is the write up for a mark VII. Lincolns OnLine | Tech Tips and Articles
since im throwing the TFS1 cam in my car im not sure if the wirring is the same and i suck.Luckly its not my daily driver.But yeah any help thanks srry didnt mean to hi jack but hey its about mass air stuff lol.
A9L (5 Speed) computer from junkyard $100-$150
A9P (Auto or in a pinch, 5 Speed) computer from junkyard $100-$150
70MM MAF from 94-95 Mustang GT - $40-$70
MASS Air wiring harness kit $30-$85
The whole thing is probably less than $300 using junkyard parts.
The conversion harness seems to work well for most folks. It avoids the compatibility problems in using a harness from the junkyard. Simple and cheap, it is actually less work that swapping the wiring harness. I have pulled the stock harness out of a wrecked car and it was like wrestling a big python.
If the idea of moving & soldering wires scares you, here's a list of compatible Mass Air wiring harnesses.
Copied from bbunt302
Just for reference, here's a list of all the compatible years:
89 harness should work for 86-89 as long as you're using mass air.
90 harness will only work in a 90. (B/c of air bags and dual dash connectors)
91 through early 92 harnesses should be compatible (single dash connector, fuel pump relay under driver's seat)
Late 92 through 93 harnesses should be compatible (single dash connector, fuel pump relay under the hood)
Larger MAF to go with Mass Air conversion:

The 94-95 harness and computer are completely different fron the Fox body counterparts. It would take a major effort for someone with very good electrical talents to make the 94-95 harness and computer work properly.
The list I posted is the best data that I have to make a working swap.
