NOTE: 

Wire indexes are identified such that 

even numbered index numbers are on 

the lower wire entries of the terminal 

block and odd numbered index 

numbers are on the top wire entries. 

Since terminal block 60 is a ground 

block, terminal blocks 61 thru 72 

shift while still maintaining the same 

top and bottom configuration.
