NO, remove the FuelMax.. you do not want to be running it in conjunction with the dual fuel pump setup as the controller runs directly off the battery and not the FPDCM, so there will be a discrepancy in voltage and cause the secondary pump to have a different DC and ultimately fuel flow than the primary, and you don't want any of that drama.
To answer you original question, yes, reversing the wire at the connection point on the FPDCM will restore it back to factory. The exact colors you mentioned.
As for your Katech unit, is that thing brand new? Have you installed it yet, or what is going on with all that? It's important to you is why I am asking.
