Hey all,
I recently had DEET repair the original FWM assembly/wiring harness/coils for my 1975 DT175. Beautiful work, of course! However, I had the parts off the bike for so long, I don't recall what the wiring looked like before. This bike did have a spark and ran prior to the flywheel sheering off and destroying the wiring. I have no idea if the lights worked. This bike is fairly new to me and the PO had no idea about any of it. Picture 1 is the harness coming off the flywheel. Pictures 2 and 3 are harness ends under the seat.  The blue end was cut and taped to the bundle. I know i didn't touch that. Can anyone advise on if these bullets connect to the wiring harness, and if so, how? I thought I recalled the wiring harness from the flywheel running towards the front end of the bike, and an empty band seems to support that idea, but I don't have any empty connections that I kind find up there. I am mechanically inclined, but wiring diagrams make my head spin. My goal for now is just to get the bike running again. Don't care about lighting. Here are the colors I've worked out. Please correct if necessary:

Black or Black/White: kill switch/main switch from handle?
Yellow: lighting?
Green: to battery?
Red/Green: to fuse/battery? 
Sky Blue: Neutral Switch?
Brown: Horn?

 

Sorry, wiring colors I identified in the first post were for pictures 1/2. The Green/Yellow and Brown wires taped together in picture 3 are for the stop switch?

Please see attached a photo that I have "nicked" from the CMSNL website of a new harness.

I would imagine that the first photo, showing DEET's replacement/refurbishment, mates with the block connector on the right of the photo (then sits within the rubber boot).

The wires to the left of that will mate with the ones from the rear lights and indicators.

The longer two go to the rear brake switch.

The two red females will connect to the fuse holder (this has two males).

The single black and red attach to the battery terminals.

The black ring connector usually bolts to the frame under one of the coil mounts, with the coil going into the female connector alongside it.

Not sure what the four pin block connector is for (ignition switch?), but it should be obvious from what's on your bike what it connects to.

Brown, brown/white and black is flasher relay.

Red and white is rectifier.

The final bunch of wires match up in the headlight bucket, probably with the left and right switchgear.

Hope that this helps!

 

Super helpful thanks! Exactly what I was looking to find and for some reason could never locate a picture showing that block connector. The wires around that block on the right appear to be the others I took pictures of, but for some reason I cannot locate the block. That's an obvious connection to the flywheel harness female block, and yet I cannot locate it. I'll have to pull the battery and other under seat items when I get home. It must be pinched underneath something somewhere. No way I would have cut it off. Thanks!
