Must have fixed polarity DCC to all tracks approaching the TT. Wire up auto-reverser from DCC bus to the brush rings feeding the TT bridge tracks. Wire up loco decoder from DCC bus to TT motor. Program it (on the main) to an easy to remember loco address (like 99). Operate it simply by selecting that loco address. [Some decoders may need to be temporarily connected to the programming track in order to re-program the address CVs. You may want to do that first.]

You will find that the TT motor wants to be run at <6Vdc otherwise it rotates much too fast. Use Programming-on-main to set up the motor decoder to run at lower speeds by adjustment of CVs 2, 5, & 6.
