hey, mom saw my F150 with the mod to make the fogs stay on when you turn on the brights- shes got a 05 250 King Ranch and wants to mod that- any of y'all got that done? similar to the 150? if so which relay?

thanks all

I installed a seperate switch on the dash and at first hooked it up to the yellow wire on the back of the headlight switch like I did in my old 2000 F150. But that did not work with the high beams due to the electronics control box under the dash wiring. I then just bypassed the control box and hooked the wire from the switch straight to the fog lights wire on the output side of the control box. This worked with both the low and the high beams, but the ignition did not turn them off. I then installed a relay of my own that is turned on by the ignition so I don't have to worry about leaving the fog lights on and killing my battery. If anyone else figured out the stock wiring, PLEASE let me know.
