I just got my GHL dosing pump (4 heads) without controller.
The info sheet that came in the box specifies a connection cable should be delivered with the pump.
Unfortunatelly, in my box there was no such cable.
Is this cable supposed to be there or should I have ordered it separately? If the latter, which is the code-name of this cable, as I couldn't find it in the list on GHL site?

A quick reply would be highly appreciated!
