Alternatively, working from the schematic, is there any reason not to simply connect the Transistor Tester to the ADS using the ADS-supplied MTE cables?
Pins 1-18: use the 18-pin MTE cable provided for the DIO.
Pins 19 and 21: use the 2-pin MTE for AWG1
Pins 20 and 22: use the 2-pin MTE for AWG2
Pins 23 and 24: use a 2-pin MTE to +/- V
Pins 25 and 26: use a 2-pin MTE to ground
Pins 27 and 28: use the 2-pin MTE to Scope2
Pins 29 and 30: use the 2-pin MTE to Scope1
More connections=more room for potential error, but if I don't have a Breadboard Canvas handy, that would work, yes?
