Thanks Scoop!
So, I'm guessing I'll do this:
1) cut off the actual plug on the molex connector
2) wire the red to the +5v to the P360 #1
3) from the +5v of P360 #1, run a wire to the +5v of P360 #2
4) repeat steps 2) and 3), but for GND (black wire) instead of the red +5v
Does this sound right?
Cheers,
Mani
