I bought an 86 mustang gt roller. The cpu it has on it is a A9L in which its clearly not factory so im guess an 89 harness is there any way i could connect the gray and black connector on driver side strut tower to the 86 harness
So the 89 harness is not plug and play. If the harness is in good shape then I would see if I could locate an 86 harness buy it and sell the 89 harness. Add the mass air conversion wiring to the 86 harness and move on.
