To get the pins out you need to get a very thin screwdriver and prise out the red piece of plastic in the plug that goes to the ecu then the pins pull out quite easy,as for map sensor goes just copy ofab loom wireing to get your wires the right way round for the map sensor as ofab and ofac run two different plugs and i think motorsport developments do the supressors and should be able to help you out with wireing it in.Hope this helps.
