Thank you both for your suggestions. Here's an update--and one little, but baffling, problem.
At this point, the installation is complete, except I haven't done anything with the lighting yet. For that, I'm planning to follow Henry's advice: remove the incandescent bulbs and connect LEDs to the Cruise Commander.
Here are photos. As you can see, I decided to keep the original horn board. I connected it to the power on the Cruise Commander. Now I can still use the horn--and it does work--if and when I run the engine in conventional mode. For the antenna, I connected a wire between the two posts for the pantographs.
Now for the results:
- Most important, TMCC operation works as expected.
- However--and this is what's baffling me--conventional operation is fine at my workbench, with an LW transformer and a few pieces of track. BUT, on my layout, using a Legacy Powermaster--with the switch set to conventional--the reverse unit doesn't cycle, leaving the engine sitting with its lights on.
Any ideas about what's going on? Am I forgetting something?
