Don't do it! I tried doing that crap and lost some money. 1996'* have to have 1996 PCM'* ..supercharged ones atleast. It sucks, but you've gotta do it the right way.

Please, shine a little light on your supposition. (For those of us who think otherwise.)

I've got most of my research done, out of 160 wires, I only have two left to find where they go. I will be putting this in spreadsheet format, you can expect a full write up sometime next week. BTW- There are other differences than just the tranny codes, a few wires will have to be changed. Good news though, it will work, and I am going to go through with it.

Ya, as long as the 97pcm will support all the necessary things like perf shift, perf ride, trac cont, etc, and it should if it'* an SSEi, then you will be set. A homemade harness which utilizes the common trans wires (shift sol A, B, TCC, TCC PWM) and adds new wires for -65 specific controls, will be needed. And the -65 trans plug.

I have an Excel spreadsheet of the PCM Pinouts, including connector diagrams, Pin Wire Color, Circuit No., Function, Component Connector Cavity, DTC(*) and Affected Possible Symptoms From a Faulty Circuit for the 1996 and 1997 Bonnevilles.

Email me if you'd like this file.

Cheers,
