I just installed the complete LED Plasma light upgrade from WCCC on my 69 XR-7.
Everything works perfectly except the Hazzards. When i push the button in nothing happens. I if i press the brake pedal, the dash turn signal lights come on while its depressed.
I confirmed the polarity of the wires at the Flasher, swapped with the turn signal flasher to confirm it was good.
Yeah if this is Vic’s stuff he will help you… I had a issue with my electronic sequential unit for 68 Cougar as the Hazard lights would not work correctly either but everything else worked fine… Come to find out my unit was built in 2012 and didn’t want to work with LED lights as well… I emailed Vic and he had me ship him the unit and upgraded it, sent it back and now works 100%… Great guy…
Had the exact same problem and mentioned it to a club member who had just done the conversion as well.
He had found that from the factory the passenger side flasher wiring is often switched in the plug. It works with a traditional flasher, but has this exact symptom when you use the new LED flasher. Pull the two wires out of the plug (one red, one white), flip them, and plug back in the flasher. Voila.
I used a flat tip jeweler’s screw driver to depress the tab on the wire ends so they would pop out of the plastic plug socket.
