Double check you VIN. If you have a 5 wire ignition switch, your bike is probably a C200, forerunner to the CT90. Is your motor an overhead cam (CT90) or does it have pushrods (C200)? The wiring diagrams are quite different. If your 5 wire ignition switch wires are red, yellow, white. brown and red over blue, you have a C200. If so and you want to know where they go: otherwise check C200 wiring diagram, not CT90.
red-battery power when key is on for accessories, horn, blinkers, brake lights, coil, etc.
yellow- from alternator
white-from alternator
brown- to tail and speedo illumination
red/black-to battery positive (fused)

Mine has to be 67 or later has 2 spd gear box in stead of double sprocket like my old 66 had is over head cam but no factory signal wiring and 5 wire sw could be 68 ?

That doesn't make sense. Bikes with 5 wire ignition switches use the ignition switch to turn lights on and off. That's why one of the 5 wires is brown. On CT90's, as on other Hondas, the light switch is on the handlebar. Is one of your 5 wires brown? Magneto bikes, like most 50's and 70's, use a 4 wire ignition switch, (2 wires short out the coil) but most 90cc bikes only need a two wire switch, since all they do is provide switched power for coil, lights, blinkers, brakes, etc. Maybe that switch was not original and only two of the wires were hooked up.
