20100 LED Kit

Like I asked before, are you wanting to have these always on or to light only when the lighting controls are active?

I must have missed your earlier request for clarification, sorry.  It would be nice to have an option, if possible.  If no option is avaialbe, then I would choose to have the them on when the lighting controls are active?

Since I don't have this unit, and the couple page instruction sheet doesn't say much about the operation of lighting, how do you turn the lights on/off?  I would guess they're controlled by the lighting outputs of the R2LC in the unit.  If so, I'd connect the AC input of the LED controller to that output and ground to control the lights.  If there are no incandescent bulbs across that output with the change, you'll also want to connect a .01uf 50V ceramic cap across the lighting output as well to trigger the lighting triac.

GRJ, thank you.

Could you send a picture of how the cap is to be connected.  

Right from the lighting output to ground.  I don't have any pictures, but for LED upgrades to TMCC locomotives, I solder it right to the pins of the R2LC connector on the motherboard.
