Hey Ernie.

This is the kit I'm hoping by to use.

It's a 12v 2A power supply for the 5m strip. The bench is 3m long. 3/5 of the length so maybe 1.2 A current draw?

The idea would be to dig into the PIR circuit and find constant 12v, tap it to power the fader box and then tap the PIR out put to feed the trigger.
