I think the included directions suck, so I'm posting a photo here of how I did it.
Basically remove the +5/+12 transformer, rectifier, and oil cap. They're all junk and it makes a great spot to install the switcher. Screw it down. Now run the AC wiring to that distribution block with quick disconnects. Now the switcher is protected by the main fuse AND controlled by the main power switch.
I would have preferred to mount the adapter on the left, in the original 90412 spot, with pcb standoffs and a small homemade wiring harness. The existing wiring would be in the correct place and it wouldn't be hanging off the power supply. However I really did not like how the wires would get soldered to those tabs.
Anyway, here's an idea for doing it cleanly on your own machine.
