The supplied 20-pin terminators are identical, but the pin assignments for 8x32
are not (rows 1-4 are on J24; rows 5-8 are on J25). The terminal
numbers—corresponding to the headers—are shown below. Pay careful attention

You must fabricate custom cabling to make row signal connections to the central
16 pins (3-18) of these headers, using the pin assignments below. The supplied
blue terminators accommodate 22 AWG coated wire, fitted to “crimp-to-wire”
contacts with latch tabs (FCI part #76357-301LF or equivalent).
