I went to the wrecking yard and they couldn't give me an interchange list for a tccm. They didn't have any 94 S10s. I looked at ones from the interchange list aleekat posted. The tccm isn't wasn't behind the kick panel on the passenger side.
I watched a Youtube video while I was there. The guy said tccm could be in 3 different places. He was working on a 2001 Chevy something. I forget the model. I also read another forum post from a guy who said he heard his tccm clicking from behind his glove box.
At this point I don't know what else it could be besides the tccm, but finding it on these other years and models may prove pretty tough.
