There are also a few different wiring variations between the 96 and the 97 that have to be addressed, I would elaborate, but my notes are at home.

Edit: the 4t65 has 11 vanes and the 4t60 has 9 vanes.

The PCM couldn't care less if the fuel gauge is connected or not on all my Fiero 3800SC 4T65E swaps I have never connected it. I am using a 97 GTP on my 3800SC 4T65E Trans Sport van swap and it also doesn't care the most it will do is throw a code that only a tech II scanner will catch, won't throw a check engine light. On my Fiero swaps I do not connect anything to do with crusie, ABS, traction control or even A/C when its not used and the PCM still doesn't put on the check engine light. Dan

The PCM diagram you sent me was still really useful. After I cross referenced the 97 and 96 PCMs I found that the only pin differences have to do with the new fuel sending unit wiring and the 4t65. Other than those couple of differences, the 96 and 97 are identical PCM wise, except for programming of course. That'* when I came up with the idea to just leave the sending unit pins on the new PCM and wiring harness open, eliminating the majority of my wiring issues.
Now I just have to figure out why on the '96 the BCS is only connected to circuit 639, while the '97 has an extra pin for it at D2 on the C101 connection that hooks up to circuit 239. :?
