My TH8A breakaway connection has died. Before it was just flaky; I would have to connect at a specific angle, and tighten the thumb screw at the perfect strength, for it to work. But now it won't stay on. I never use the DIN connector, so I'm thinking I'll just chop off the two DIN ends, and permanently wire it to the USB connector. Does anyone happen to have a wiring diagram? Thanks.
