Hello,
The map only has a electrical connector, it does not have a vacuum hose for your vehicle.
The MAP sensor is located on the top of the engine next to the intake manifold.
See attached diagrams for your reference.
If you can upload picture of the hose we will be more than happy to assist to figure out where it might go.

I have attached the MAP sensor diagram as well as diagnostics for your reference.
Please let me know of any questions.
Thank you.
