On my 94 Blazer, once I got my computer out, there were 2 other boxes attached to it... Once did not have a label on it, but had a similiar connector as the computer does and measures 3" X 5" X 1.5", and the other, much smaller (3.1" X 2.9" X .6") is sorta foggy clear plastic with 2 smaller connectors. P/N on that box.

My question is hopefully simple... What are the other 2 boxes?

Thanks in advance

The small metal box is the transfer case module, and the smaller plastic one (I am made to believe) is the cruise control module.
