I have a 93 lt1 car, and I want to convert it to a 94-95 pcm. Is this a plug and play deal under the dash? I know I'll need an engine harness and PCM...what else?

 

i have done the swap and i am still working alot of the little bugs out.you have to change a few pin outs and have to add a power for the pcm from the 3 plugs that go in to the car and i am trying right now to get my data plug to work right now if you need any help just pm me

 

Ive done the swap and been running for over a year and half now. theres about 6-7 wires under the dash that you need to move or splice to the correct location. I saved my paperwork. oh, and dont mix up the vss and fuel pump relay ckt's as they are the same color. thats the one mistake I made. I got mine to fire right up after that. and you can run the data link serial wire from the same place (passenger kickpanel connectors) and run it to the diagnostic connector because in a 93 it comes from the headlamp harness and under the steering column but it will be dead when you make the swap. Instead jump it from the other side of the dash in the 94+ harness.
