The instructions provided dealt with programming the board "personality" (i.e., setting the machine model) once installed. It had nothing on the actual physical installation. YouTube videos were of minimal assistance since my exact brand/model year wasn't shown and happened to come apart slightly differently. However, the basics of the repair were clear:
- unplug the machine, remove the bolts holding the top together (in my case, a pair of long bolts holding the top onto the machine, and 4 smaller bolts holding the back panel on for easier access... which I didn't realize until I was 2/3 of the way through the disconnect)
- disconnect all of the current connections; I was worried about tracking which connector went into which slot, but it really is not necessary because every connector is unique. You can't plug them into the wrong slot. A few were a bit challenging to remove, though, while trying to be careful not to apply too much force, and one tube was short enough that the whole setup had to be pretty close to its final position in order to reconnect it
- remove the 5 bolts holding the board onto the machine's top
- take the old control board out, put the old one in, reset the control board bolts, and insert all the new connectors (be careful not to tangle the wires or something may end up too tight for flexibility, carefully put the whole thing back into place and put the external bolts in place
- plug it in, follow the instructions for setting the personality (mine defaulted to the right setting), and good to go!
- reverse the process - put the bollts back into the board.
