or at least a wiring diagram for the rear brake light??? Cause i dont know how the brakes engage the brake light.

Yes, there is a chain tensioner. On mine, you have to loosen the rear axle carrier bolts, then tighten an external tensioner. I have an old parts wagon that is either a 125 or 175. It has a tensioner inside the chain case, it's another sprocket that is either spring loaded or you have to manually adjust it. Not sure which because I've never messed with it.
As for the brakes engaging a "brake" light, I don't think they had them, just a taillight.

anyone got pics of the tensioner?

Here's the pics. I stand corrected about the axle carrier bolts, you don't have to loosen them, just the ones on the tensioner.
