Hey all!

I have an Atlas Master Silver SErise F-M Trainmaster and I'm trying to get the decoder in. Which way does it go? Here is the far away view of everything lined up in the proper direction.

Here is the close-up of the connectors on the loco.

I know that the triangle on the bottom right pin is supposed to be pin 1.

Here is the close-up of the DCC Decoder.

So which wire goes into pin 1? Is it the grey or orange or does it really matter? Don't want to kill a decoder or loco tonight.

I'm gonna drop this this into the HO forum as well.
