getting ready to change out the pcm on my 02 Saturn sl with one that is from an 02 sl1 so it can be flashed to pick up the factory cruise I have installed. The dealer could not reprogram the pcm that came on the sl. I need the location of the theft system relay in order to swap the pcms.

 

And the "dealer" can't find that information in all the GM literature they have?
Look at the underside of the fuse box covers inside and outside for fuse/relay mapping. I'd think it'd be there.
