Headlight upgrade

[Nightpath]

I'd almost bet that the power wire for the fog lights are attached the wrong relay. They should recieve their power from the same relay as the low beams.

In the diagram I posted I bet that the fog light is connected to the high beam (orange) instead of the green.

another project to add to the list.  Thank goodness it'll be summer soon and i can get out of my tiny cold and cramped garage.  thanks for the links and the diagram.

Good job. I used the same headlights and harness on my dad's Oldsmobile Delta 88 about 3 weeks ago. I had to make some changes. I had a heck of time with the highs and lows working properly. The high beams would sometimes stay on after turning them off. Other times the low beams wouldn't come on. The harness only uses one fuse and the low beam relay gets its power from the 87a pin on the high beam relay. The solution was to supply power to the low beam relay with it's own power wire and fuse to the battery. In doing this it fixed the issue and he will at least have lows or highs if one of the fuses blow.

Thought I would add a response to this old post. I've been having goofy things happening to my headlights such as lack of low beams, high beams not turning off, etc. After reading this old thread, I figured I would do this modification recommended by Eaglefreek 11 years ago (which I said I was going to do at that time lol. Better late than never). Whe I went to cut the wire from the 87a pin on the high beam relay, I the wire pulled out of the connector very easily and looked like it was poorly connected from day 1 ( see picture). I finished the modification and now have consistent low beams but still having issues with the high beams not wanting to turn off. I've replaced the floor mounted dimmer switch but that hasn't solved the problem. Will do more investigating next weekend.
