1997 bravada wiring

I just bought a 97 Bravada and behind the drivers seat on the floor is a single loose electrical plug. I can' t find any female plug for it. THe driver lumbar and speakers in the back doors don't work now. Is this a connector for one of those?
thx

The power lumbar device has given some people trouble due to electrical shorts in it's wiring. Unplugging it might have been somebody's quick fix.
