Edited the first post with a short cut link to the post above about the second test ride thoughts. Someone who might be interested in the combination, but doesn't want to read through 11 pages of my drivel, no longer needs to. Also changed the title to better reflect how the rig actually came out.
I don't think this is "unintimidating or beginner friendly". But it is a whole lot of fun. 🤩

Worked on the lighting today.
Overall I feel kind of "meh" about it. It works but definitely lots of room for improvement when the head light gets added.
Not convinced the Running/Turn Signal lamp under the front lip of the sidecar fender is easily visible for oncoming traffic. For now the bike's right front turn signal will stay active.
Happy with the rear sidecar light (added an 1157 LED bulb). Temporarily using a passive 3-2 wire trailer converter to get Brake/Turn & Running lamp.
Under seat of the sidecar is a mess. It will all get cleaned up when the air compressor and battery is mounted.
I'm using part of the excess discarded trailer harness just to get a lighting ground through the SAE harness. lol
Made a sub-harness to plug into the factory harness for brake and running light.
The way it is setup one connector is disconnected for the sidecar lighting harness, and the SAE connector is unplugged. The right turn signal lead then gets plugged back into the oem sub-harness via a bullet connector.
Both the SAE harness and the sidecar light harness slide out under the fender, and stay with the sidecar when it is removed from the bike. Super easy to do.
For the sidecar lights, the front running/turn signal is a Harley Davidson aftermarket kit. Just lengthened the harness. Originally thought this was going to be the "hot setup", but I don't think folks are going to be looking under the front lip of the fender. P-clamps would be a better way to secure the harness.
The original rear sidecar light has some interesting wire colors.
Yellow is ground
Brown is brake/turn
Green is running
Blew a fuse before realizing my mistake. lol

If it's a light then it's should be visible, in the dark anyway.
People may need a second headlight to be sure in the day.
Otherwise just weave your wa6 down the the road to make em nervous.
It's kind of hard to do the old "two motorcycle headlights split" trick from the movies with a sidecar. 
Illegitemi non carborundum est!
