The easiest is if you make a wire frame the size and shape of the film area
de pinhole "sees" and erect it on the camera, right on top of the "pinhole
plane", then make a "eye-let" viewer, sorry that's the best name my poor
English came up with, it looks sort of like this, only vertical and with the
round thing at the top ---O that eyelet should be positioned on the
camera, right on the "film plane" and the circle should be centered with the
wire frame in front. As you can notice, the idea is to "reverse" the
configuration of your camera. If you cant mount the eyelet and/or the wire
frame on the pinhole and/or film plane (respectively) you would have to
reduce or augment the size of the wire frame in such a way to have the same
angle between wire-eyelet-wire.

Hope my explanation is not confusing
