i have a 89 irco and i just swaped out the wireing harness from under tyhe dash with onbe from a 90 or 91 camaro. i want to know if the VATS connection is the samne or did they change the pin config or something. or did they change some wireing in the connection to the ECM. just want to make sure that the wireing harness will wpork because i am having to hardest time trying to get the car to work with the new harness in. thanks

Steve
