I just picked up a wiring harness from a 1990 5.0 mustang along with the computer. I only had time to take the section that begins at the brain box, and ends on the drivers side shock tower, and includes the injector section. I was not able to get the front light harness, or any section from under the dash or inside the car. My question is, will the harness section that I have plug into the 2.3 mustangs light harness, and under dash harness, or will I be better off returning for the rest of what I left behind? If anyone has any experience with this, please share your findings. Thanks in advance.

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)
Computers from 89-92 are all the same. Look for the A9L sticker on the back cover for a 5 speed that matches your requirements. Example: E9ZF 12A650 AA" with the A9L code.
