here is the link that i used but its for 04 to 08 so it might work the same way for ur 01

 

I have a 2008 F-150 FX4 super cab 6.5' bed with the auto sensing headlights and factory fog lamps.
I bought a set of 8000k HiD bi xenon headlights from intensehid.com
I too had the same problem with the fog lights back feeding into the highbeams and making the indicator light to glow slightly.
After checking out a few forums and having my friend look up the wiring diagram for the fog relay.
We opted for the "Bambi Mod" to solve my problem.
We located the fog relay in the fuse panel. It was gray in my truck. Pulled it out, found pin #1 and bent it back around so it wouldn't make any contact when the relay was plugged in. Took a female spade connector, attached it to the bent #1 pin, taped it off for extra protection. Connected a wire to the spade connector, and ran that wire to the grounding bolt below the fuse panel. Wa la. Fog lights now work with the factory switch in the parking lights, low beam and high beam.
Fixed my fog light back feeding problem.

 

I'm not sure on that. I really wish I could run my fogs and park lamps at the same time.

 

just look for the fog relay

 

im not sure how u would run them properly to the parking lights

 

That's basically what you are doing when you bend the #1 pin of the fog relay.

when you turn the parking light switch on, and pull the fog light out, they come on. they stay on as long as you have the parking lights and the fog light switch on... for high and low beam too.

I turned mine to auto lights, and when I unlock the doors, the parking, headlamps and fog lights come on. when I lock the doors, the parking lights and just the fog lights flash.

 

oh ok yea thats what mine does i thought he was wanting to have it where when u turned the **** to the parkin light then the fogs come on to with out pulling it out, i got confused there somewhere

 

I would get either 55w 5000k/6000k for the best light output. If you do get some for your fogs get 35w and a rating below if you want the color to match.
For example 55w 6000k will be similar color to 35w 5000k. I have 55w 5000k headlights and 35w 4500k fogs and to my eye they match perfectly.

Also when you do get them dont forgot to reaim your head lights and diable the perimeter lighting.

yea its important to reaim them because there bright and especially if u have a leveling kit then u really need to reaim them, idk what the right way of aiming them but i just got on a flat road and aimed them where i thought were good and they seem to be workin out for me and havent had many problems with other drivers flashin me.

 

Haha. My truck is old, I don't have perimeter lights. Lol. But if I did, why shut them off?

 

How do you turn off the headlight flasshing when locking doors on a '02 Screw?

 

HID just look a little took jap to me

 

Thats because the majority of people run 6000K. It has a slight blue look to them. The best visible light comes from a 4300K. A pure white when looking at them.
