Some yes, some no.

Remember, the 1995 and earlier used SBECs or SMECs; the 1996 is a JTEC, completely different CPU and with OBDII coming in for 1996, some changes in the cab harness and the bulkhead harness also.

OTOH, all you need to add is the two extra injector wires, and swap to a V8 ECU, for the wiring.

well I've got the 3.9 transmission and I didn't know if I'd have to change the wires on the trany to fit the v8 trany. Just trying to get all my ducks in a row before I commit cause my daily driver...
