Use an M12x1.5 to a #4JIC fitting for the air at the ICP location - any hydraulic shop should have one. You can order them from a lot of places on the internet.
To command the IPR valve - you can use an old ipr connector from an old harness wired to a cig. lighter plug and only keep it plugged in for 2 minutes not to damage the IPR. I have been told you really can go longer and not damage it, but I like to be conservative.
Try asking a tech at your local Ford dealer, maybe one will be nice enough to snip one off a harness thats laying around.

Without a scan tool to take active command of IPR duty to 100%, you can do it by having the key in the RUN position, and jumping pin #2 of C1381c (the middle of the three PCM connectors between the driver side battery and the inner driver side fender well which requires the battery cover removed to access) which will be a yellow wire with red stripe. This is the ground side wire to the IPR.
