1971 DT1 250 restoration - electrical help!

Hi all, first time posting here.

I recently dragged this DT2 250 (with a 360 motor) out and plan to do a light restoration. First thing is obviously making sure it will run. For that, I believe I need:
- Main switch (where to source?)
- Flywheel

I have the manual and wiring diagram from the files here on the site already.

Any other thoughts or feedback? is this a good first start? I am having trouble sourcing a main switch - any recomendations?

Edit: Looks like I cannot add images either by upload or hotlink. I guess you'll just have to imagine a very sorry looking machine with parts missing, especially the chopped off main switch with bare wires hanging off the frame, and a disconnected magneto with loose wires (but at least they aren't chopped off!).
Flywheel is missing, and I don't know how to test the mageto. It looks like someone tore in to it for an ignition problem, but hard to say for sure.

Welcome! You can't post pics until you've had 3 posts. You'll need to link via 3rd party like imgur or Google photos. Imgur won't work if you're in the UK unless you come in with a vpn.

DT2 would be 1972, you're title says DT1 1971? there are differences. Check the vin on the frame and motor and head on over to the tech library/vin numbers to see exactly what you have. Switches are getting harder to find. I may have a few. Flywheel i definitely have some of those laying around. You only need the black wire coming from the stator to the coil to make spark just an FYI.
