To those who have done the headlight fog light mod, I have a few questions. For those who haven't, here is the link that I am referring to.



http://www.svtlightnings.com/svt/foglamps/foglamps.htm


1. When you splice the #2 and the #12 wires, do you cut the wires? Or are you just connecting them together to make the two incoming lines go into either position?

2. Is the purpose of splicing the wires together to make the fog lights work when the high beam lights are on?

3. Where can I get a 3M splice connector and what do they look like?

 

I'll attempt to answer your question. As you stated, I'm not an electrical guru however, I have performed the mod. PERFORM ALL WORK AT YOUR OWN RISK!

To answer your questions...

1. No, no need to cut the wires. You're simply using the later mentioned 3M splice connector. I'll explain the connector on #3.

2. The purpose of splicing the wires is to make the FOGS work with the PARKS. However, by performing the mod, the FOGS will work with your HIGHS if you want to use them (if the switch is pulled out for fogs to work).

3. 3M splice connectors. They're SUPER easy to come by. Wally Hell (wal-mart), any parts store etc. The look like a piece of plastic with a flap. Inside the flap there's a piece of metal. Basically, you lay the wires inside the flap, close the flap, and lock (snap the two sides) together. This LOCKS the wires in and when you snap it together, 'splices' the wires so that the metal in the connector is touching both wires and thus, splicing them.

Did that make sense? I hope that helps. It's a great mod... I highly reccomend it! The fogs and parks look GREAT together!!!!

Don't fret, the mod is really simplistic. I was VERY nervous when I started the mod because I'm electrically stupid however, once I got the switch 'filed down', the electrical work was a BREEZE. Take your time and follow the directions to the T. They were good and, to my memory, I wouldn't have changed anything.

Feel free to post questions or comments. I might be able to help out... plus, I know A BUNCH OF PEOPLE have done this mod....

GOOD LUCK!

 

Thanks RockPick.

That was the information I was looking for before I started this mod later today.

That definitely makes it clearer for me.

 

Glad I could help. I'm on and off the board all day thus, if you run into a problem with the mod, feel free to post questions... I should be able to get back with you pretty quick.

Again, good luck!

 

RoskPick knows his stuff, just what he says! I did it a monthago and LOVE it! But, just like you said, the fogs stay on with your H-beams, be careful, thats illegal here in Pa., so your local; 5-0 may be on the look-out if they are bored enough! Good Luck!----medic

 

p.s.- if you have trouble "filing" down the plastic, i heated a screwdriver and cut away the plastic by melting it with the hot flat blade screwdriver, worked really well, i was afraid to slip with a box cutter or a file and mess uf my hand, or worse yet! MY TRUCK! ---medic

 

Didn't know about the fogs and brights being illegal. Wonder if it's like that here in KY...hrrm... I'll have to check on that. Interesting observation...

The mod mentions cutting the plastic faceplate off of the switch... I opted NOT to do that. I simply went out and got some hobby files and went to work on it. I took a while to file down but, I'm SUPER with the results. I hate box knifes... I have 5 stitches on my palm, RIGHT NOW - AS I TYPE, from one of those damn things. Long story... another thread.... another time.

Also, as the mod mentions, DON'T CUT THE ARM INSIDE THE SWITCH... I had a buddy that wanted to take the shortcut to filing it down and simply snipped the arm (you'll see what I'm talking about when you examine the switch carefully). This made the switch clumsy. It would turn 'FULL CIRCLE 360 Degrees' and just generally seemed crappy. He ended up dumping around $50 into another switch to fix his 'shortcut'.

GOOD LUCK AS USUAL!

 

i agree def. do NOT cut the arm, i would never have the ***** to do that!, taking the faceplate off was gutsy, but seeing there are little tiny tabs to line the plate back on made me feel confident about doing it...so i did, a little superglue, you never know it was off...hey different strokes for different folks. Some guy posted on here about splicing the #5 and the #12 together, with no switch mod., which supposedly puts your fogs on ANYTIME your parking lights are on, i wasnt down with this, i do alot of idiling with my parking lights on at fire scene and stuff, no need for the fogs to be on...but another idea....

 

Well, I have the laptop out with the wi-fi in the SCREW. The webpages were a great help. However, I ran into more problems than were indicated by the previous posters.

I thought my 2001 would be the same as the 2000's, well it is not.

Minor adjustments though, and I have the fogs working with autolamp, park, and high beams. Way cool.

Will post upload pics I took with the differences in the 2001's.

 

Just a few variancies in the 2001 Supercrew Gen III.

1. The light switch has three metal rataining clips which hold it into the dash, (top, bottom and left side). The light housing was much harder to remove than was anticipated.

2. The faceplate of the switch must come off. The housing is sealed and has no access to file down the switch. The face plate was held on with about tweleve 1/8" plastic posts (retainers). It simply snaped away from posts (retainers) with a little pressure. After the mod was finished, I melted the posts with a soldering iron to make the face plate secure again.

3. The housing has three black retainers that must be depressed in order to remove the switch from the housing.

4. The switch has a "light tray" which directs the light from the housing to the faceplat to illuminate the icons on the front of the faceplate. This has to be removed for the mod. It can be replaced after modifiying the switch and the plastic retainers
melted to secure it back into place.



The mod is very cool. After the electrical wire splice, the fog lights work in the autolamps and park positions. They also can be turned on with the high beams.



Total time: 1 1/2 hours. Mainly because the switch was hard to get out of the dash.

Would highly recomend this mod, just use caution to not scratch dash when removing light switch.

 

It's not impossible... I never removed the faceplate on my switch. I've got an 01 as well...

The good thing is that you completed the mod. Glad you like it.

CONGRATS!

 

Went to the Mpls/St. Paul Auto Show a few weeks ago here in the Twin Cities. Looks like someone from Ford must have figured out EVERYONE was doing this mod. The New 2003 Excursion I sat in had the same headlamp switch yet the fogs worked in ALL the postions (except off.)

The new Thunderbird had the same switch with a variable off-time delay. I'm thinking of trying that switch if and when I can get my hands on one. (Althought I'm sure that won't be for quite a while.)

 

For a 2002 Screw, you can take the switch out, splice the #5 and #12 wires without taking apart the switch, and the fogs will work when the parking lights are on. But there is no way to turn them off?

Thanks.

 

Is there a way to get the high beams to stay on with the low beams for a bright effect? Is this legal?

 

I'm pretty much positive it could be done however, I'm also pretty much positive that it's not street legal. The modification page shows the wiring schematic...might be able to figure it out from there.

I'd definately check into local laws before making a permanent modification though...
