The order of wires is correct and use either block. The most common
block in a 66 type arrangement is a 66M50 where each row of pins
provides two pair. The left side of the block is the input, the right
side goes to the station wiring and a bridge clip spans the two middle
terminals. 110 blocks are often used for pair counts above 50.
