What's needed to use an SMPS1200 is clear. What the best implementation is, for any one of us, remains an individual decision.If we keep beating on this we will figure it out. Thanks for all the information so far.

A. Just need it to run? Use the Purifi cable and put the other end on it as described, above:
One may simply insert the free ends of the EVAL1 J3 cable into the proper holes of the spare plug body to get an operational amp system using SMPS1200 J5:
B. Want to also use the nAMPON and nFATAL interlocks? Then provide either a full ribbon cable to the SMPS1200 J4, or adapt to it starting from the Purifi cable, as described, above:
Regarding wiring the free ends of the Purifi-provided J3 cable to J4 of the SMPS1200, the provided wires appear to be 22 AWG. Most IDC sockets accept only 26-28 AWG. The largest I have found DO extend to 22 AWG, and accept discrete wires, but are pricey. For example, the 3M CHG-2010-J01010-KEP:

Even so, we still need two more wires, with crimps, to complete a 5-wire cable from the EVAL1 to the SMPS1200. @JimM found those here:

Alternatives?
1. Do not use the provided cable for EVAL1 J3, and make up a ribbon cable with crimps on the end to load into the spare 7-position J3 plug; or
2. SPLICE the wires from the Purifi J3 cable to wires of a ribbon cable that mates with J4 of the SMPS1200.
