There is a slight case change I think in '94. Also, the ones backing a diesel have a seperate computer to run than the TBI harness in the gas version. Sorry if this does not help, wasn't sure what you were looking for.
91-93 bad harness in valve body easy update tho.
and 96-97ish moved 1 cooler line to rear of tranny case for better flow of hot fluid to cooler.

make sure you match the case's up for what vehicle it is, i made this honest mistake about a week ago after having it all rebuilt and everything and bolted to the block... bad carma i guess... your looking at the mounts for your eutral safety switch aka manual lever position sensor and the mounts for the shifter bracket.. also make sure of cooler lines and stuff like that cause there is two different ones.....
