Anyone Know What This Hole's For?

Getting ready to install my wiring harness for a TBI system. Found this hole with what looks like a factory grommet, but nothing going through it. Located under the heater box. Sorry, one of the pics is sideways. This is a factory A/C 72 Blazer that I don't remember ever seeing or taking anything out of. I'm asking cause if nothing important goes there, then I'll enlarge it some and use it for my TBI. Thanks

Thinking of putting a 50 Chevy cab on a 76 Chev 4 WD pickup.
