Thanks, John (@johnb). I finally found a photo of the real motorcycle that showed the junction box. The only problem was that the model part wouldn't fit there. There were no locating pins or tabs, but I finally got it to fit with a little minor construction. Just another day in the life of this kit.
Thanks, Anthony (@anthonyricco). I'm a standoff modeler. All of my kits look wonderful if you stand far enough away. :o)
Thanks, Rory (@rory). Luckily the technology in this WW2 motorcycle looks similar to other older technology I have seen. My first car was a 1956 Chevy that I paid $200 for, and I did all the work myself. I couldn't do that now. Put something modern in front of me and I'm lost.
