Chase, how did this go? I suspect it went just fine.
I have looked at this b/c I will be doing the same thing Chase is. The 96 and 97 pcms both have identical pinouts. The 96 wiring harness and pcm connectors are compatible with the 97 pcm. The only difference is the additional 8 wires for 4T65E control. The -60 and -65 sharesomecontrols and the wires are in the same pin location in 96 and 97. All that is needed is to splice in the -65 connector and add the necessary wires in a custom harness with pcm terminals added to the appropriate pin locations in the pcm connectors.
