PIAA fog lights not working

Hey guys,

Recently purchased a 2010 Tundra that had some PIAA fog lights installed.
I was in a hurry and didn't check if they worked. They don't.
I tried changing the H3 bulbs but it didn't do the trick.
The switch does turn on and off just fine. Connectors inside the lights are clean. There are no evidence of severed/broken/rusted wiring anywhere.
It looks like there is a harness that connects the lights directly to the headlights (the light on the switch turns off when I turn off the high or low beam).
Any idea where I should be looking to possibly solve this issue?

Thank you

 

Check for voltage at the light. There should also be an in-line fuse wherever that harness picks up power if they didn’t use factory wiring.

 

Checked the voltage at the lights and I'm not getting anything. The relay seems to be working. Fuse is intact.

 

Voltage at the fuse on both sides?

 

I'm getting a reading there too

 

If you have voltage at the fuse trace your wiring from there to the bulb to find the short.
