I have officially completed my first ERR upgrade. I finished the wiring and got the shell back on with little problem.
I tested the marker lights and John had suggested but could not get them to work. Not sure if it was still a wiring issue or a programming one. I decided to connect them to the track power terminals. I figured they are always on anyway and they will be a indicator of when the engine is on a powered track or siding.
I took everything apart and cleaned up the wiring, had to replace the power wire coming from the pickups (it broke), and re-solder one of the motor leads. Better at that point then after I put it all together.
Once that was done I made up the JST plugs for the lighting. Now I can completely remove the shell and not have to cut any wires. I may update the lighting in my other two beeps and could swap shells depending on what I'm running.
Here are a couple pix of the final assembly. The three wire harness is the headlights and the two wire is the markers.
This was a fun project. I'm going to do an AC commander in my Santa Fe F3's next.
On the left is the lighting complete, and the right with the sound commander installed.
And here's the final product on a test run.
