Instructions:

No more need to assemble your wiring harness,  that's already done for you.  You just need to sort out a power connection, to whichever 5v source you have available. An assembled power cord is included, with convenient alligator clips on the ends.   To generate proper logic signals between your CPU board and this display, they must use the same power source.   The test points on your CPU board are an excellent source of power for this purpose.

If testing a CPU board that uses 6 digit displays, plug both wiring harnesses into the bottom headers at P2 and P5, then flip dip switches 1 thru 4 down with switches 5 thru 8 up on the DIP switch block on your display tester board. 

If testing a 7 digit CPU board, use headers P3 and P4 with switches 1 thru 4 up and switches 5 thru 8 down.

Connect to the CPU board using the appropriate headers.  On System 3-7 it's a simple straight connection.  On System 9, note the header connection numbers as the connectors are mirrored right to left.
