Asked by May 13, 2016 at 12:43 AM about the 1993 Saturn S-Series 4 Dr SL1 Sedan

Question type: Car Customization

I have 1993 saturn sl1 that i am swapping a 1999 saturn
sl2 engine and transmission in. I have the whole 1999
saturn sl2 and it runs and drives but will not pass dmv
inspection due to a rear end collision. I know that this is a
project but my question is since I am using the pcm and
wiring harness out of the 1999 saturn will I have to
reprogram the pcm?

1 Answer


If you have the complete "Powerpack" engine, harness etc. and old vehicle you won't have to reflash the PCM... 1993, S series uses standard ignition KEY so you don't have to re-code this!
