No you will have to transfer the 99 engine management wiring and computers into the 93 for the systems to operate as they should. Sounds like a real project, good luck.

Reason being is the '93 is an OBD1 computer and the '99 is an OBDII computer. Like they say above, you need the computer & wiring harness from the '99 to run the '99 motor.
