Adding a backup light to an On30 Bachmann Shay

[Kasman727]

I have searched extensively for any information that would help me add a backup light to the Bachman On30 two truck shay, without any success.  The locomotive came with factory installed DCC and sound.  Several questions:

1.    Has anyone done this?

2.    Is it possible to add a light using the existing board?

3.    Does anyone have a circuit diagram for the Bachmann board?

4.    Anyone know what the unused C2 solder pads on the main board are for?  They do not appear to be used.

Sorry for so many questions, but seeking some guidance here.


Thanks

For anyone interested, I opened up my Climax to see how it is wired and discovered that it utilizes the same electronics as the Shay.  The Climax has the backup light soldered to the C1/C2 contacts on the board, and I will be wiring my Shay to the same contacts using a Bachmann light that came with the Shay.
