Jason gives good advice. I would like to add:

The three pin plug for the MAP sensor is available from your dealer. It may take a bit of prodding, but the connectors and pins used in the stock harnesses are available separately.

The methods used to secure the pins into the plugs vary from connector to connector. It can be frustrating, as some of them are like a clever puzzle designed to drive you insane before you crack the code.

I have never disassembled the MAP sensor plug. If you have a mechanic friend who is familiar with automotive connectors in general, he may be able to help out with special tools and techniques. This is the best reason to buy a new connector and pins, because you can easily understand the pins before assembly. The assembled one that is on your car now can be difficult to take apart unless you understand exactly how to release the pins without damaging them. And any damage at all will generally render them unusable: this is a very critical connection for proper engine operation.
