I know w/ all the JK hackers on this board, somebody has already done this simple little mod. I've done it to other vehicles in the past but figured I wouldn't have to figure out how to do it on the JK as someone had already done it.
Soooo, If you've wired up your JK so that the fogs stay on when you turn them on, regardless of if you have your high beams or low beams on, let me know how you did it! Thanks
i added them after i bought my jeep cause the one i bought didnt have em. put em on thier own relay and switch. now they are on when i want them on and off when i want em off. i can also turn off my headlights, therefore also turn off my rear lights at night and just have them on allowin me to run stealth mode
I don't have a write up or anything, but from a logical standpoint, you simply need a relay between the two circuits.
That is, the high beam circuit provides the trigger for the relay and the power side of the relay is tapped into the fog lamp power side. Ideally, the same fuze that powers the fog lamps would run the power side of the relay, so that you had one point for troublshooting power issues, but a separate power supply with it's own fuse would work as well.
Find any of the diagrams that show how to hook up aftermarket fog or spot lights and wire it the same. Just substitute the high beam as the trigger (may be called input or switch) and the output side of the relay goes to your fog lights.
