haha, well, you want the capacitor bank + connected to B+, and the capacitor bank B- to the B- in jacks picture. Also, you want the sum of the paths from Capacitor + to Diode cathode (the output of the arrow), diode anode (input to diode) to IGBT collector, IGBT emitter to capacitor bank B- to be as SHORT AS POSSIBLE!!!!!!!

The precharge circuit isn't shown. YOu basically need to apply full voltage to the capacitor bank, through a resistor. So a separate relay that allows the caps to fill up with a resistor in series, and then once the bank is full, you close the main contactor. The control board I'm sending you has 2 relay controls, so you can have all that done automatically.
