Ignition switch pigtail

I have a '69 version which has the side clips to hold it onto the later type switch. Your '65 might not have that provision on it's switch. It has provision for 6 wires, but, currently only uses 4 of the sockets. The plug/pigtail has about 3"of the wires sticking out, but, they're not in the greatest of shape. The plastic plug looks ok though. You may be able to use some of the wires, and, if you're careful, you can reuse just the terminal connector if you need to. I believe those "fishhook" terminal connectors are still available new if you can't use these or the ones on your wiring harness.
