Next to one of the large capacitors are two holes that look like a jumper should be placed. to run in pwm mode, should those two pins be shorted?

Only if you are planning on using an external pwm input, so in your case yes.

How do i get this to work with a 24v cpap motor using 5v pwm?

In order to enable PWM there are a pair of solder pads that need to be jumpered. The label silkscreened above them on the PCB is J1. They are adjacent to the two white shrouded 5 pin JST connectors. I put a two pin 0.1” pitch header on mine so they can be mated with a shunt jumper. The speed adjust pot needs to be turned all the way counter-clockwise and the PWM signal is connected to the pin labeled 0-5V.
