I have an old Chilton wiring diagram manual that covers nearly all makes/models available for the 1964-68 model years, and can still be useful for one year older or newer vehicles in general. If you're in need, or you'd like to have a set for your particular vehicle, hit me up on a PM, and I'll photograph and transmit copies to you. However, if you would like hardcover copies, I can do that, for a ten dollar charge, and we can iron out the particulars in the PM. Thank you!
