For any one that has bought a Soundtraxx Programming Track Booster (PTB-100) and hooked it to a Zephyr xtra, what or how did you connect it to the power supply? Is it hooked to the zephyrs in some way i am not seeing (as the zephyr's uses a plug not a wire system from the power supply) If I need a seperate transformer can I use an old MRC tech 2 power pack and pull from the accessory voltage?
