- COMPLETE engine harness + ECU

This is where it gets tricky, the ECU needs to be reflashed to remove the NATS system, then the harness needs to be rewired. I sent my harness out to Fever Racing in tampa florida. To the best of my knowledge they are the only ones in the country doing this conversion. This alone cost me $1,950.

At this point its plug and play, my motor is up and running in the car and i'm happy.
