MTH Premier Santa Fe Hudson MUX Board Issues (20-3144-1)

Daniel J. GonzalezOGR Forum Member

The title says it all. I have taken the shell off and can see no apparent issues that stand out to me. At first, I could not get the Cab/Head/Marker Lights to work. The smoke unit works fine and having it on or off does not affect the functionality or lack thereof in this case, of the lights. I have made a video to illustrate how, after removing the MUX board and touching the rear pins, I noticed the lights would flash and even stay on. I have tried to wiggle every single wire you can think of but nothing gets the lights flashing like touching the back of the board. What should I do from here? Do we have a pinout I can follow to make sure I am getting the correct voltages?
