I believe your MAP sensor is located passenger side of engine behind the throttle body. It is a rectangular looking thing mounted on top of plenum.

Then you can trace wires/hoses if need be.

You don't have a MAP sensor. '85-'89 used MAF (mass air flow) which is completely different. MAP was used from '90-'93.
