Engaging the fan clutch???

As I've tried not to blow you guys up with questions I have yet another one. Currently my fan clutch is not engaging for the A/C. This is due to the Cummins ECM running the fan, and the Ford ECM running the A/C. Thus causing extremely high pressures on the system and warm/cold/warm air in the cab.

It was suggested I tap a switched ground into the clutch's Br/Or wire to engage the clutch. This did not work. Is there any way to engage the fan clutch manually until I figure out a way to teach the Cummins ECM that the A/C is engaged?

Much appreciated, TIA
