PCM is the computer you need the correct updated '99 sl2 engine PCM HUGH difference from '93 to '99 Regards


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.
