Having trouble with Baja Designs wiring plugs.

That bottom photo, the bottom most pin looks like it's bent. If you can take a closer photo with more light i can verify that. But sounds like that's your issue. IF it's bend you'll need to remove it, cut the pin off and put a new one on.

Where are you installing these lights outta curiosity?

If I paid Baja Designs money for lights and had to fiddle around with the harness, I'd be pissed.
