We've updated our mounting plate for the Falcon V2 to also support the V3 controller along with a host of other add-on options (expansion, pi, PSU, etc). The new mounting plate plus everything else you need to build out your controller - pigtails, power supplies, extensions, enclosure, clamps and more can be found here:
