1. Connect wire from Command Base to "Black" fixed Output of TIU.
4. Connect "red" Fixed Output 1 to center rail, "black" Fixed Output 1 to outside rail.
5. If you are running conventional you need to power the TIU via a separate power supply or run jumpers from Fixed Input 1 to Vari Input 1. In addition, use Vari Output 1 not Fixed Output 1. If you are running everything command then initial set-up for the TIU is correct.
