Open XB-2 by loosening 5 big screws on bottom. Remove keyboard by loosening 7 medium sized black and brass screws on bottom and inside organ. Disconnect keyboard from mainboard plug connector. Remove nylon wire straps on cable harness, but DO NOT cut any cables, just unplug all connectors! Keep MIDI jack board. All other XB-2 boards may be discarded (or sold for big $ on ebay).

Remove all boards inside including supporting rails. Retain cables and headers from power supply, front panel, drawbars, LCD and volume/reverb pots. Locate pink/black/green/orange strain and separate black/white strain to now unused connectors. Obsolete XB-2 power connectors may be cut off as pictured here or may be left open and tied up securely (see next picture). Insulate cut wires with shrink tube. DO NOT cut long orange/black/green/black/yellow cable!

Install large HX3/XB-2 mainboard as pictured using wood screws and 5mm plastic spacers supplied with kit. Connect drawbar, large 5-pin power plug, LCD and button cables to matching connectors on LCD interface board as pictured. Connectors are all different size and cannot be confused. Obsolete power connectors may be left open and tied up with wire straps. Re-install keyboard and connect to 15-pin header on HX3/XB-2 mainboard (right side). Be shure not to pinch any cable.

Install new jack/preamp board board as pictured. Re-install MIDI jack board and connect to jack/preamp board's 12-pin header. Connect long orange/black/green/black/yellow cable to matching 5-pin header on jack board. Connect Leslie 11-pin connector to matching header on jack board (right side). Connect gray and red/brown/white cable connectors to matching headers on jack board. Connectors are mostly different size and cannot be confused. Connect 26-pin flat ribbon cable to HX3/XB-2 main board and jack board.

Re-install MIDI jack board and connect to 12-pin header on HX3 jack board, left side. Attach decals and lettering on front and back of organ. Note for alignment: Headphone jack is on same position as before. Plug in organ and test all functions. Re-install top lid. Now you're done!
