Like Catt I have no experience with that model, but what in the world does the frame have to do with the installation? Are you comfortable with soldering? If so, consider doing this install yourself. There should be wires from both rails from both trucks coming to a pcb. In all likelyhood the colors of the wires won't meet DCC standards, but don't worry about that. You'll be able to see which rail each wire is coming from. The decoder will have instructions for which rail gets connected to the red decoder lead and which to the black. I think red is to the right rail but am not sure, I myself just check the diagram in the instructions during installs. In any event, the orange and grey decoder wires go to the motor. If the loco goes backward when the throttle indicates forward, reverse motor leads. I use alligator clips to check prior to soldering. Connect the lights and you are done. This all takes 15 minutes.
If there is some factor I'm overlooking let me know, or if you want to give it a go and have questions, ask away.
