I have an '81 G5. I was having light issues with them being dim and I've sorted that down to needing a new switch. All contacts were cleaned up and the normal issues checked into with brushes, rotors, grounding, and rectifier tested. I replaced the switch and am having a terrible time finding which wires to attach to which wires. The Vetter fairing wiring and new switch wiring are easy. It's the bike wiring that's making my brain cells hurt. Every schematic I've found seems to have color codes that don't match my bike!

This is the diagram I've found for the bike:
image storage apiIt shows using the brown wire for a couple things. There IS no brown wire! The gray wire is for the passing lights and should run through the relay. When I hook the passing lights wire to that gray, nothing happens at all. I can add a hot wire to it or my test light from ground to it and it activates the relay. I'm thinking other wires are not connected right to complete the circuit. No clue. Electrical genius I'm not! It's also showing a blue/black wire that's absent (or more likely a different color) that should be the main headlight wire and on switch.
Any constructive help would be appreciated. Which wires go to which???
