Lighting the AUX tender?

If you can't do it in software, there's always rewiring it to track power.

The tender harness is wired for reverse light. So you would have to see if the sound file had other light controllable via dcs Active.  Example ditch or markers as an example on a diesel.  Then you would have to change the wiring to that output pin.  Most likely the lights are not on for a steam file.  This would be something a tech could do easier since they have the bench testor to see what outputs are active, and know pin outs.  

Easiest for you would be a CV board to keep it lite. G

What about tapping into the headlight circuit? It'd be on all the time though.I'm assuming the main circuit  board and headlight wires  are in the first tender and  not sure what connection goes to the aux tender.

I don't think the headlight comes back in the tether to the tender.

Gregg, that is possible along with interior/cab light. G

You'd probably have to do some minor wiring in the locomotive to get the signals back there, right?  That's not a major issue, but something to do.

Don't think so john, If the main circuit board is in the tender, that's where the pins (connection)  for the headlight are, tap in there. Take a look at the upgrade schematic for the kits.All the pin location are the same .And as G mentioned interior light would be much better,

Good point if it's in the tender!  However, since he's mixing and matching parts, I kinda' figured the electronics was in the locomotive and not the tender.

I don't know for sure either john.

Tapping the lights into another pinout on the board sounds like a great idea. I will look at PS2 steam upgrade doc after Christmas. Thanks

If the electronics are in the locomotive, there are normally a few leads going back in the 10 pin tether that are unused, so there are plenty of options.

The electronics are in the tender i know this because I had to buy the tether to control the aux tender light and protocoupler. The user manual, for the berk listed the tether as included, but I had to add it.

The output for the front headlight will support one more light if you wish to do it that way.
