Wiring Array Matrix
Here is the easy way to wire each switch. I have 3 color-coded
groups consisting of 6 arrays. Simply wire one lug from each switch in that
array to the next in that array. For example, Array A,1- wire one
lug of switch 1 to 13 to 26 to 40 to 45...
Each group is color coded with the wire I used (orange,
navy, sky blue)
A,1 1 to 13 to 26 to
40 to 45
A,2 2 to 3 to 5 to 14 to 29 to 43
A,3 6 to 7 to 9 to 15 to 20 to 32
A,4 10 to 27 to 33 to 34 to 37 to 47
A,5 4 to 11 to 16 to 21 to 30 to 38
A,6 8 to 17 to 22 to 35 to 41
B,1 12 to
39 to 42 to 44 to 57
B,2 18 to 36 to 46 to 48 to 52
B,3 19 to 31 to 49 to 50 to 51
B,4 23 to 28 to 53 to 54 to 55 to 58
B,5 24 to 25 to 56 to 59 to 60 to 62
B,6 61
This is Ribbon 3. In parentheses, I have the correct pin out that belongs in the circuit board.
C,1 (C6)1 to 2 to 4 to
6 to 8 to 10 to 12 to 18 to 19 to 23 to 24 to 61
C,2 (C5)14 to 15 to 21 to 26 to 33 to 35 to 44 to 50 to 54
to 62
C,3 (C4) 29 to 32 to 37 to 38 to 40 to 48 to 58 to 59
C,4 (C3) 20 to 30 to 34 to 41 to 43 to 45 to 49 to 52 to
53 to 57 to 60
C,5 (C2) 5 to 9 to 13 to 16 to 22 to 27 to 42 to 46 to 51
to 55 to 56
C,6 (C1) 3 to 7 to 11 to 17 to 25 to 28 to 31 to 36 to 39
