Add Horn to Lionel Command Tie-Jector 81445 - Diagrams

In 2005 I began installing Electric Railroad Mini Commanders in MTH operating cars. They worked great and were reasonably easy kits. When I started looking for a Tie-Jector horn kit, an Electric Railroad kit seemed to be the best option. The Electric RR kits had changed in 12 years and I had no idea what to order to make up a kit.  When it comes to electronics installations I am strictly a "dot to dot" person.  With a complete kit and wiring diagram I'm reasonably safe.

Thanks to Jim Sandman I was able order the correct Electric RR parts to make up a kit that would work on the MOW Tie Work Car to add sound and a backup light to my Tie-Jector. I needed a Command receiver circuit (with antenna) and a Sound circuit kit (with speaker).  The Command Receiver (Dummy Loco Controller) circuit I ordered is relatively new and came with an interesting diagram (see first diagram below).
