Diagnosing sequential blinker quirks

Hi guys, I’m restoring a family heirloom, I’ve got it running really nicely and I’ve begun to work on my lights. Yesterday I received the plasma LED conversion kit from West Coast cougar. I installed it and everything is working kinda sorta. Here are the problems I’m having

  • when my driver side blinker is on the passenger side lights up dimly and flashes as if my hazards are on. The same thing happens on the driver side when I turn on my passenger side blinkers

  • when I have my markers on my turn signals work perfectly except they do not sequence

The second issue does not bother me as I can still drive it like that, but I would like to address the first issue so I can get it on the road. Any thoughts to what it could be or how to diagnose? My thoughts are a faulty turn signal switch although I’m just guessing and could very well be wrong.

The systems are quite different from year to year. What year is your Cougar? I think we posted at the same time… Thanks. I don’t know much about the '71 though.

Yes it’s a 1971. And that’s alright I’m just listening to any thoughts you guys might have on here

Did you watch the video on the WCCC website ? Very informative especially on the phat cats 71/73.

Did you replace the flasher cans with the new LED flashers? On a 73 you need 2, one for hazards and one for turn signals. They are polarity sensitive, that kicked my butt until I re-read the flasher instructions lol

Did you replace the front turn signals with LED?

Did you replace the marker lights with LED?
