You can now solder the seven wires to their correct places on the main board as indicated on the correct diagram and table below:

Bare ModChip	Assembled ModChip	Connection on main board as indicated on diagram
Pin 1	RED wire	RED circle with a 1
Pin 2	No Connection	No Connection

Pin 4	BLUE wire	YELLOW circle with a 4
Pin 5	GREEN wire	RED circle with a 5
Pin 6	BLUE wire	RED circle with a 6
Pin 7	YELLOW wire	YELLOW circle with a 7
Pin 8	BLACK wire	RED circle with a 8
