1972 Demon fender top blinkers

Just deleted my last post, I was totally wrong. That bullet connection is woven in with the side marker light, which drops down from the headlamp plug harness. There is a hole in the bottom of the headlamp bucket for the side marker harness. I am not an electronic guy, don't know if just tapping into the harness works.
Give it a try with a test light.
