On page 25 of the manual for the K2 it explains the instructions of mounting the diffuser, my question is,,,,, d2 and d3 are led's,,,,,it is not marked on the diffuser which is d2 or d3,,,,,,so i guess i can mount either end to the board. Is this correct? Sorry, this may sound very basic, but before i solder i need to be very sure of this. thanks to all in advance.... john
