So I sold my 1990 GT and used the money to buy 4 more Foxes. '93 and '88 fourbangers for my everyday driving, then I gotan '88 and an '89GT. '88 didnt have a title so I swapped the motor over into the '89.

Its the stock 5.0 with the Auto. The thing I didnt realize was that the '89 had the heater core, computer, and wiring harness removed, so now Im in the process of taking the harness and computer from the '88 and changing it over. Ill be back with questions as they arise once the task gets going good.

The 88 harness and compuet are for speed density, your 89 has mass air. You can use the harness and add the mass air but computer won't work

Since everything under the hood of the '89 came out of the '88 will it still require the mass air? The computer, harness, engine, tranny, steering column,is all out of the '88.

you can use sd in the 89 if you want...you'll just need the 88 sd harness

Thats the plan, use the '88 harness and keep it SD
