What you normally see is the headlight will be off and the cab light on if the S-C isn't connected to a TMCC lighting output. The smoke fan should also be off if you don't have smoke power. The cab light should be on if there's no chuffs being input.

Hmm, the cab light has me worried...... its an led with a 470ohm resistor and diode......ahhh just saw my issue, I should have a lower value resistor since thats a 12vac output right?
