CAstle Link Quick Connect and Field Programmer?

Hi there,
I have a mamba monster ESC with a castle link quick connect and I was wondering how to connect the castle field programmer card?

There seems to be no voltage sent from the ESC to the quick connect, hence inhibiting the use of the field card through the quick connect cable.

Is it possible to use an external power source to power the field programmer ( via a y harness) and also send power through to the ESC for the purpose of programming in the field?
I dont really want to connect directly to the ESC cable as it is neatly tucked away and defeats the purpose of quickly programming in the field.
