The sidelight issue had me scratching my head too. If the side light comes on when headlamp switch is on, but not when ignition switch is in park, you probably have wrong wire to front sidelamp. It should be a brown wire, NOT brown/white (these supply tach and speedo). I did not realise that the power for sidelight/rear lamp takes a strange path, from r/h handlebar via brown/white wire back to ignition switch terminal TL1 then to TL2 which is the brown wire, then to pilot/rearlamp. when ignition switch is in park position power goes directly to TL2 for parking. If you look on the wiring diagram i sent you it makes sense. The odd blue/brown wire you have would have gone to fusebox on 400/550 so not needed on your 500.
TBH if Ted had done some close up shots and concentrated on the wires from the switches we could have worked it out much easier. You need close pics to work out the traces on the wires, you can't tell what's what from a distance. Bad Ted
Ken, i cant tell the colour at close distance without my beloveds sewing magnifier!
