Have been struggling for years to get my motor swap legal in CA. I was told by the shop that did the conversion that they used a 91 motor and wiring/ECU to match the 91 car i had it installed in. Welp, they used an 89 and the smog ref bombed me on the inspection. I now have to figure out how to switch the ECU from an 89 to a 91 to be CA legal. What all will i need to change to modify my 89 harness to add the 91 ECU?
P.S. the shop that did my swap went out of business due to scamming other customers similar to what they did to me, so there is no help there. I have a 5 speed manual trans, mated to what i now know is an 89 5.0 Mustang V8. I understand they are REALLY close in almost every way. I have already acquired a 91 harness and ECU.
Any gurus who can help me track down what needs to be done to make this work?
preemptive thank you, to any and all who can guide me.
