I’ve got all the wiring done and tied with a bow for the control board.  There are more control circuits on the board than I expected.  I bought a 15 terminal plug expecting to fill 5 terminals, instead I have 11.  In addition to the 11 below, I have two sets of 144 VDC 10 gage wires.  One pair is for charging and is always hot while the second pair is for the DC-DC converter and is only hot when the key is turned.  I am planning to have a key lockout.
The picture below shows all the circuits, but here is the list:

1. ground for items that can share a common ground
2. KSI & under controller fan are activated when the gas pedal is pressed
3. Contactor + runs when the gas pedal is pressed
4. Contactor - runs when the key is turned
5. Cooling fan runs when the key is turned
6. Potbox +/- connect to the pot box (gas pedal)
7. Ammeter +/- connect to the ammeter in the cabin
8. Volt Meter +/- connect to the voltmeter in the cabin

Hmmmm…it may have been possible to combine the KSI & Contactor + circuit and the Fan & Contactor - circuit.
