I have a 1985 iroc-z which I bought and pulled out the motor which was a 350 TPI that was swapped before I bought it. The tranmission is just the 700R4 If all works out well I will becoming across a 1994 LT1 motor that I would like to swap in there. I know that I have to buy the vats module but I was wondering if the wiring harness from the old motor is still useable, would I be able to use that one? because I believe that they have an electronic control to the 4l60e. so I was just wondering if that would be at all possible. instead of spending the helashish amount of money on a new wiring harness.

 

research and search the LTX and LSX swap boards listed above.

You have to use the LT1 wiring/computer. You don't need a VATS delete module, it can be programmed out.
