Ok Chuck I have the time and items to try this out. I think I have it correct but check it out for me.pins 6,7 get power from either the track or pins 6+8 from T-1, then pins 1,2 get the signal from T-1 orange and brownwires and pins 3,5 go to the motor/train. Question is since the pins6,8 on the throttle(T-1) were intended for the lamp on the train engine, might I be overloading the T-1 taking power from here? Maybe the trace for pins 6,8 can't handle 1amp, since it was design for a grain of wheat bulb which draws 30ma? The intent here was to protect the non replaceable T-1. I don't want to burn one up playing around! I will give it a shot running it threw its own BR first. steve
