If i remember correctly wen i did an lt1 swap in a 91 GTA convertible i had to send the PCM away to get the VATS taken out and i used the painless LT1 wiring harness it was a long drawn out ordeal but the car worked pretty good wen we got it up and running

It should be very easy to use the stock Harness.

What's done to the Car already..as far as how far along in the swap are you with the wiring?

Put power to the Pinks and the Oranges.. the Pinks are circuits that have power with the Key on. The Oranges are constant power from the Battery. Everything goes through the Fuse Box.

Isolate the Pink Wires for Bank 1 and Bank 2..then put power to them from the Fuse Box, Ignition side.
