That is what I am confused about. Since this truck did not have ACC on original ignition switch, there isn't a 12G Brown wire in the wire loom.
That is why I was unsure of two things:
1. If the brown/white wire still joins to the brown wire on the ACC position of this new style plug. (You said yes, but where would it have joined originally on a 67 style plug that didn't have an ACC wire?)

2. The plug I replaced did not have the brown ACC wire, new one does. So there is no brown wire from plug to fuse panel. If I extend brown wire from plug to fuse panel, where does it connect and will that make the ACC position work correctly?

This diagram shows the 12 gauge brown wire going down to the fuse panel and the black arrows point it out. The brown/white stripe is just below it and it runs to the inside of the firewall block.

The 12 gauge brown ACC wire goes to the back side of the fuse panel and powers the wiper,TS, heater, and backup light fuses. Hot with key on.

This is a lousy picture but it's the only one I have.

Your key switch shows a small red wire with the main red power wire on the same connection. i don't remember what that powers but it is full time hot.

Re: BROWN WHITE Striped wire from the Ignition switch Burnt what can cause this?

VetteVet, I am following what you are saying thanks a lot!

I guess where I was confused is I was thinking that a 67 would not have that brown 12G wire at all, since it did not have an ACC position from factory.

By what you are saying, I should still have a 12G brown wire under there somewhere because something would have to power the wiper, TS, heater, and backup light fuses. Am I correct?

By this diagram that you posted earlier, it looks as if on a 67 the Brown 12G wire would have connected to the IGN tab whereas later years it would connect to the ACC tab?
