Hello everyone. New in N scale and to the forum. Very limited knowledge of DCC other than the basics.

Just bought a  Bachmann Spectrum USRA standard tender which I am using  in a kitbashing project with the Minitrix K4.  The tender has a mounted pc board with 6 pins.  Is this a DCC decoder and can I use the appropriate pins to run power to the loco?  I just want to run in DC mode for now and possibly DCC later. Am wondering  whether a micro connector is available which would make the wiring neater. Also what is the recommended Micro-trains coupler for this tender?
