Do a thread search. This has been discussed a LOT here. I think you have to get a 3.4 motor ECU to go along with your new motor, wiring harness and headers.

Just found this over on Renntech...

I also have a PDF (1.8 Mb) with pictures and a full account of the swap. If you will PM me with your email address, I'll send it to you.
