Installing the switch contacts

As the switch boards are installed in reverse order switch 1 triggers the 
highest note and switch 49 triggers the lowest note. 

That also means that the key assignment is in reverse order. Keep that in
mind should you wish to play with the configuration!

Cut the ribbon cables to length and strip the wires.

Switch board 1

 (20pin connector):

Wires 1 (red stripe) gets soldered to the common bus bar, see picture.

Wires 2 gets cut.
Wires 3-18 get soldered to key contacts 49-34.
Wires 19 and 20 get cut.
