I have a 1968 Mustang Coupe that I have been restoring over the last three years. I finally got it to the point of working on the wiring. I replaced the brake light switch and when the brake pedal is pushed, it stops flashing like it is supposed to.It has power coming across the switch. I have running lights and blinkers at the rear. I did find two wires that I can't find where they go. It is a solid brown wire and a yellow wire with a black stripe that look like they belong in a connector coming from the steering column. It is a fixed wheel. The bulbs in the rear are good. I also checked all the grounds that I could find. I am thinking it might be the blinker assembly, but the rest of it works.
Any help would be appreciated.
Thanks,
Ken
