I was a little confused when I 1st got the gbfans boards too, but the last poster is right , the wand and pack lights receive power through he ribbon cables so no other power connections are required except the battery to one of the sets of terminals on the sound board, doesn't matter which one. they're all in parallel
So essentially just what the documentation says to do. as silly as it sounds, a big part of me is really apprehensive about slicing open the male side of the blue brick connector and wiring it into the board. i just don't want to screw it up. Also if i wanted to mount a switch on the bottom of my motherboard how big of a switch should i get?
You can buy the connectors from radio shack (labeled size M) to make a pigtail to connect to the battery connector on the blue brick. a lot safer than cutting the battery wires, you have to be very careful of shorting hr battery wires
RS also sells the small toggle switches to kill the power
I modify all my blue bricks by removing the switch and led and wiring the charge and output with wires to reach a "spengler plate"
