Fog Lights - 12v at plug with switch off

[61Hawk]

I decided to work on my fog lights on my '89 GW today since they were rusted out. I bought a set of amber LED lights with two wires (red & black) same as the originals. When I plugged them in they came on... headlight switch and fog light switch are both off. I checked the plugs and I've got 12 volts at each plug.


Anything I need to look at other than putting in a relay? I don't know why I've got power at the plugs with the switch off.


I don't know if it matters but I upgraded my headlight harness to the Serehill harness, the two relay version not the three relay version with the fog light option.

I looked at the wiring diagram and see this is already set up with a relay for the fog lights, maybe the relay is just stuck closed.

Relay was sticking.

Good find! Glad it was an easy fix!

Good fix. Where did you order the led lights? Going to need one for uncle's Cherokee after we finished installing the brake kit and I'm a paid spammer for a major internet parts house on the current Silverado project. He brought a Chinese knock off before and it is acting up after about 5 months.

They don't come with a wiring harness, just two lights. I ended up cutting off the wires off the old rusty lights and spliced them into these lights.






These were my second choice, but I decided I didn't need the wiring harness.
