Yes should work fine, the a9l is a five speed mass air computer. All u have to do is move some wires and plug them in. Don't forget to take the vacuum line off the map sensor next to the vacuum tree on the driver side. I think it's a BAP sensor on non mass air, but once it's unplug it will be a MAP sensor.

Yes. A mass air conversion on your 88 will require an 89-93 mass air computer along with a mass air meter. You'll also have to change your cold air intake if yours won't accomodate the meter.

As long as the 89 gt still had the mass air computer in it then yes the harness will work. The computer Should have a computer code designation like A9L, A9P or A3M are the most common codes used in Mass air cars.

You will need a computer from an 89-93 Mustang GT or LX 5.0. It does not matter if it is a 5 speed or automatic computer if you are using a 5 speed but if you are using an automatic you would need the automatic computer. You can not use a computer from a 4 cylinder car.
