I want to mod my Fog lights so they run all the time. Is this possible, I know some of you have done the switch mod, but I was wondering about running the fog lights with brights and autolamps. Is there a wiring diagram for this. I have a 99 F-150 with three connectors on the back of the headlight panel assembly.

 

Follow the technical article for the Lightning. I jumped wires in the last part of that article to have the fogs on any time the park lights, or more, are on. Works with autolamp too. No parts req.
