Where to connect an UBEC easily on Inspire 1

[Fabian]

As I would like to connect two external devices with a voltage of 5V to the Inspire 1, mounting an additional UBEC seems the right solution to me.
Now the question is where is the best and easiest place on the Inspire 1 to connect the UBEC to?
Do you have suggestions how and where to wire an UBEC?

Thanks for your recommendations
