Ok that makes more sense. I'm probably going to see if MTH had any of those boards in stock or I'll see if anyone here has one for sale before I try to cobble something together.
Does that PCB only act as a distribution board, or is there any voltage regulator or logic in it? If it's just a bunch of connectors and traces, then I should be able to rig something up way easier.
Still need to figure out how/where to add wires to the loco MUX board to control my additional lights.
By the way... What the heck does MUX stand for?
