If you would like them bigger shoot me a PM with your email address, I'll gladly send you them, though they are only slightly larger. I actually have these printed off. I wouldnt imagine the wiring changed too much between 65/67, but I could be wrong.
Using that diagram I would check your red/blue wiring running from the ignition switch to your starter relay. I believe that is the one running to the "start" on the ignition switch. Anyway best of luck let us know how it goes.
