Do these plug directly into my factory fog light connectors?

Yes. These are built as direct replacements—they wire into the existing fog light circuit without splicing or relay modules. Simply unplug the factory units and connect the new LED housings.

Will I need to reprogram my truck or add a load resistor for the LED conversion?

Not unless your truck's lighting module throws a warning for LED load differences. Modern Super Duty models typically handle LED swaps without issues, but if your truck was equipped with auto-dimming or a sensitive fault detection system, a load resistor kit may help. Test before committing to one.

Can I return these if they don't fit or don't work with my truck's electronics?

Returns are handled per modsupply.com policy. Test-fit before final installation. If there's a fitment concern or electrical incompatibility, contact support with photos of your setup for guidance before installing.
