Edit: Sorry for the crude sketch, but I had to erase the pressure switch in MS Paint, print to a PDF, insert that into AutoCAD, add the momentary switches, then do a screen capture. Probably should have gotten rid of most of the yellow first, but was too lazy to keep going back and forth to make it pretty.
Nicely done...Methinks my mental block is starting to crumble ...

Do check that 13-14 has continuity when the contactor is manually closed, but breaks continuity when the contactor is open, before doing any wiring though.

13-->14 open with power disconnected, continuous with contactor manually depressed/engaged
