Scrap this initial post! See my post number 7 below where I get to the root of what I'm trying to do- add LED lights to the steuerwagen function decoder

Thanks- I've seen the prior threads (maybe I missed one) but they don't cover the details I'm chasing.

If I recall correctly, the 64022 was an AC set where the pilot coach had a slider and LED head/taillights. That set did not include interior lights or current conducting couplers. That was part of the "Spirit of Germany" consist.
The new set 74042 has LED interior lighting (digitally controlled) and current conducting couplers. I do not know if that means that each coach has its own digital control or whether the lighting can be controlled from the pilot coach of the matching set.

Hi everyone,

With the day off work, I was able to dig deeper. More information, and more questions if any of you actually own a Roco railjet:

Revised problem statement:

All I need to do is figure out where to solder LED interior lighting into. My two possibilities appear to be via locomotive 2 pole coupling, or via the steuerwagen PC board. The latter sounds much more likely, but I have no idea where to solder them to on the base plate.

More factual information:

1- My locomotive, #68366, has the coupling shown with a 4 pin connector, of which only two pins are "live". The instructions - all 4 booklets included- do not indicate what these two pins/wires are for, but according to the 2010 new items catalogue, the locomotive is set up for "direction-dependent current consumption," whatever that is? Knowing the control and voltage of these pins would be great.

2- My cab control car from set #64022, despite being the "no lighting" version, turns out to have a decoder and a fancy PC Board. See images. Instructions for MY car set and the decoder do not give me any more info, but looking at the SISTER (with lighting) set instructions online, interior lighting is controlled by the steuerwagen, not the locomotive.

3- Looking at the 2010 new items catalogue, it appears my cars are the "Railjet standard" offering, and the locomotive is the "railjet premium" offering.


Does anyone know their way around the cab control steurwagen PCB? I'm guessing Roco used the same part for the version with lights, in which case I just need to learn where to solder onto it for adding my own LEDS as a function, but no idea how/where to trace this?.

Thanks in advance!

Mario - THANK YOU!!! This is exactly the information I needed!!

Please do let me know what you learn tomorrow when you check the last 2 pads.

This should make for a really easy lighting installation. I guess the only question left is whether the decoder can control them or not...

I really appreciate it...

Thanks Mario! This is really a big help.

I need to order some parts, but I think I can add lighting easily based on the information. I'll need to test the decoder mapping in my own control car as well, but at least we know the board is wired for AUX2

I looked at Roco instructions online, and they say F7 should be the interior lights. See the attachment. Also this STUMMI THREAD about your same problem?

Looking at your LEDs for the interior lighting, shouldn't they be soldered to pads 3&4 (AUX2) in order to have the digitally controlled lights go on and off with F7?
