Bob,
To add the newer horn unit, the True Blast 2, all you have to do is supply power from the center rail pick-up and the outside rail pick-up or frame of the engine. Make sure you get power before the circuit board for the center rail, like straight from the roller assembly, or your horn unit may only work in one direction.
If you have room under the shell, the T.B.2 will usually work well.
Are you familier with parallel wiring? If so wire the horn unit in parallel with the center rail power. The frames on most engines if they are metal will give a good place for the negative wire to get power from.
In my opion True Blast 2 sounds better than most other horn systems. I even put a T.B. 2 into a Lionel diesel engine that had a simple horn sound.
