5 Wire for Power Supply

But as to soldering to the "housing", then no. You solder the wire to the crimp, and you plug the crimp into the housing until it clicks

Am I right in counting 22 wires http://www.e-licktronic.com/en/content/ ... e-io-board

I've got 25 plus the insulated wires for the Master section, which will come out to 6 individual wires, 2 ground, 2 left and 2 right

5 for main power and ground
8 for J14
4 for J13
4 for J12
4 for J11
