"Communication Error" after install

Installed power fc today. Got zilch on commander until I jiggled the connection a bit. It willl only read "communication error". Have not tried to start it yet but could this be a simple loose ground or hot at the harness? Car had an old school PFS purple box I removed a few weeks ago but harness appeared untouched

Any idea? Incompatible commander? Loose connection point makes me wonder

Thanks
T

The times that I received the communications error was due to faulty cables. Constant twisting/bending caused loose connections between the wires and connector.

Once for the DL input connector to the PFC, and twice with the serial cables.
