OK, so I am tearing down our 2000 s10 2.2l for the LS swap. I dont have a picture of the pieces mounted to the bottom or the core support ( outside now in a pile), but here is a picture of the two plugs, the yellow connectors.
Thanks, that is what I suspected, but I thought I only saw one mounted in the front of other vehicles I worked on.
Googling for the service manual now.
