It maybe be possible for Milzy or WOT-Tech engineer a custom harness to make the swap plug-and-play. I'm assuming thats what Milzy needs a test car for. I just wish there was more support for the 3900. That would be a bad ass swap.

In Ontario you'd be able to classify your car as a hotrod if you have a custom engine swap.

The problem with the 3900 is trying to make two completely different generations of electronics work together. The Alero is Class 2 (J1850 VPW) based and the 3900s PCM is GM LAN (CAN) based. You may end up with different modules not wanting to communicate.
