Re: Car Starts, but not through ignition
The 1967 ignition switch did not keep the IGN line hot during crank. That is one of the reasons for the yellow wire from the starter soleniod to the coil. During crank, the starter solenoid provides the coil with 12Volts. It's not uncommon for other model years to experience the same issue if a 67 ignition switch is used. 68 and 69 model years fixed the ignition switch problem, but retained the yellow wire for a hotter spark. Sounds like your yellow wire is missing.
