Travis, the light switch CB is within the switch housing......it's rated 20 amps and the dimmer resistor is 30 ohms.
Thanks for working on it, although I'm personally perfectly happy with the TM wiring diagrams, with all the variations from year to year. Some features like an oil pressure safety switch is not present on all models. Wiring, specific for other variants should be so labeled.
All a pretty big job if it's to be useful.
I also find it interesting to see changes as they occur in time, where does the push button switch come in and how is its wiring to be shown.
What's not well documented are the ground returns, they should be labeled exactly the way they are realized on the vehicle, such as "ground" strap, "washer/screw","housing" etc, so that the return path to battery neg terminal can be followed in the diagram. Some diagrams show a little of this ground wiring some don't.
All light bulb part numbers should also be shown with wattage and/or current drain.
The turn signal pilot light should be grounded, the instrument panel grounding should be made clear....it goes on and on.
Edit: Added a sentence.
