The guys at VintageCarLEDs.com are looking into what may be causing my problem. I am sure it is not their light, but something to do with the wiring. Probably my wiring. I know very little about LEDs, but I have an idea what to look for on this. Please chime in on your thoughts.
So here is the deal: Installed the very awesome LED headlights from VintagecarLEDs.com. They have been on the ball with customer service, helping me with the install on my 75. Backdated bumpers with OEM fog lights. I wired them up and either did not document, or can't find any notes on the project. My Prosperos garage wire diagram for the 75 does not show fogs. Everything worked fine with the non-LED headlights. Fogs are only on when the low beams are on, just like factory. So my only change is the LED install. Taking a test run last night Low beams are awesome, High beams are awesome. Both need adjusting, of course.....>>> and decided to pull the switch for the FOG lights. At that point the headlights went to HIGH and would not switch back. I get the click with the blinker stalk pull, but no change on the headlights. Not sure if the fogs were on, probably not. But that is my issue. I am thinking it is ground related. Don't LEDs want their own ground? Maybe I am sharing a ground with the fogs??? Please chime in. |

No rewiring just pull the ground wire off the relay behind the panel and put it to ground.
It's the silly floating grounds that cause this issue. See Here for diagrams and pics |

See Here for diagrams and pics I did your fix 1st then did the blk/blu between the switches and the added wire from the switch to the keyed fuses.... see post 5 above. It gave the Fog switch power with the key on vs. with the HL switch on. That way you can run the fogs and nothing else. ANd they turn OFF with the key. Only doing what you suggest requires the HL switch to be pulled to at least the 1st notch. And I think the fogs stay on anytime the fog switch is pulled. Clark |
