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.
