I sent it to you privately.
Allow between three and four hours for the job. Plan on scratching your head a lot trying to figure out what the instructions are telling you to do. (The wiring diagrams are mostly accurate and actually the best way to figure out what goes where.) Bring a head/neck support as you'll be under the piano a lot. Bring a drill. Make sure the MK4 is up to date and functional. Most of what you will be doing is removing old hardware and installing new. There are far fewer wired connections in the DKC-900 than the there are in the MK4 so you'll have lots of leftovers. Have fun.
