1973 wiring

[mjc]

I just picked up my 73 cb750 k3. I running and rides good but has some lights that have problems. The wiring diagrams seen to not really March what I have. Taillight work off and on front running lights are the same. So my question is how do I know I have the correct wiring harness? I don't have the neutral safety hooked not that I want it but would like to know which wires would have gone to it.

I couldn't find the wiring diagram for a 1973, but this is the diagram for 1972. I hope it helps: https://www.honda4fun.com/dwnload/Wiring/CB750-K2-wiring.pdf

That helps be it is way clearer than what I have. The manual I downloaded is not that great and diagrams are hard to read. Thanks.
