In trying to make my  Non powered units a bit more than empty shells on wheels, I am looking at some this power distribution boards to connect multiple LEd s for headlights, instrument lights and sound systems. Would these work? They appear to be thin enough for hood units:

HOw would the LED one work on AC input  without a rectifier?

Im trying to make my wiring in these unpowered units a bit more professional looking than a rats nest.

It would work fine but I would go with version without the LED which would light the interior of your shell.  If you want DC you will need a rectifier on the input.

You can light an LED with AC using a diode and resistor.  Evans Designs and others sell them ready to go.

At 90mm (3.5”) this will occupy a fair chunk of floor space and 12 connections seems like a lot.  I agree with keeping it neat which, makes working in it easier, but I would consider some 4” wire ties to bundle the wires to a central connection point.  Also consider that things attached to your shell will need a plug/socket with x number of pins so you can separate the shell from the chassis.

I don’t know how far you want to go into this or how you run your trains but checkout this thread for a board for a whole slew of options.

If not I’d recommend putting a rectifier in for any LED’s. If you run DCS it’s also recommend to add a 22uh choke from center rail so the anything in the engine does not degrade DCS signal

Yep. I have those rc red connectors to help detach the shell from the body for any servicing.
