Default What is this box?

I need some help. I’m retiring my 92 LT1 and this black box by the MAP sensor doesn’t have a wire yet. I don’t know what this is for and can’t find information on it. Do any of you know what this is?

Evap solenoid. Basically, it sends fuel tank vapors to the engine to be burned.

My gf says "wtf? " Retiring the 92 LT1? Did you ever get the C3 on the road, or did you abandon the project for a P@#$% a$$ c4?

OP - I'm guessing maybe 'spell check' got you and you actually mean 'REWIRING'. Correct? Do you have a correct year FSM? If you do I believe you'll find wiring 6E3-C3-6 (Chart C-3). Cannister Purge? See 6C-19 (Fig 16) for component ID.
