Bowtie Boy

Just reinstalled my mail order tuned PCM, got a CEL about 3 miles down the road. Before I take it to advanced to scan it is there anything special to do when reinstalling a PCM or just plug and go? I assume the light is from my front O2's not being plugged in. Just curious if anyone else had this.

It was what I thought it was. Front O2s nothing else. Hope this helps if someone else runs into it, you wont need to worry.
