Does anyone have a wiring Diagram for adding a MARS light into a 4-8-4, 4449 with DCC??

I cannot figure out which tabs to use on the distribution board, inside! It's a clever set up, but, now I need to add MARS!!

I am trying to install an Ngineering Mars Light. Where do I connect it to the Module?

The Controller is a Bachmann EZ Command Control Center, 44901.
The Loco is Bachmann 50201 Southern Pacific 4449, 4-8-4 with DCC.
Being a GS4, the loco has the Dual Light System up Front, and the Top one is usually the MARS Light.
Right now, Both spots light up when I turn on the Power to the track.
I am very familiar with the actual 4449, and on the Locomotive, we do it with Motors in a figure 8 pattern, which would be impossible in the model.
I am not sure if I should use Incandescent or LED Lighting. Incandescent gets too hot, and LED is too White.

Please tell me how to program the DCC Decoder inside my 4449 DCC Equipped Locomotive for a MZARS Light. Is it already on the Circuit Board?

Do these Locomotives have a Can Motor, or do just certain ones?
