i bought an OEM valence w/foglights,harness & switch off e-bay supposedly for 99' on up. i have a 2000 expy and i already checked for an existing harness(not there). i have the new harness ran (lights plugged in, black wire to the firewall, red wire to the solenoid, white/orange wire & red wire going thru firewall to inside) i cant figure out the rest. there is a yellow wire & a white/black wire that is supposed to go to the new switch but now that i have figured out these instructions are for a 99' ONLY, i dont know where to connect them. ALSO ... the red/black wire that is supposed to connect to the red/yellow wire in the dimmer switch harness?...where do i connect that one? (if i didnt connect that wire, would that let me run fogs w/hi-beams?) I KNOW the headlight switch is different from 99' to 00' ( i have the right one for my truck- 00') PLEASE HELP!!!

 

hotrod22,

Got your email, I was finally getting a chance to answer today, but since you posted it here, I reply here in case another member needs this topic.

First : The only diagram I can find of hand is my 2001 EVTM. I can;t find my service DVD at the moment ( burried in my office somewhere ), so I am working from the 2001 F-150 EVTM.

Here we go with some ideas.

Black Wire on Engine Side : Ground for Relay ( maybe the driving light, depends on how the harness is put together.
Orange / light green is to the Battery Junction box for hot at all times connection, this must be the Red wire on the 99 harness This is power to the relay for the driving lights in a 2001 ??
On a 2001 The Connection to the Driving lights is Tan / Orange for the power, and black on the other side.

The Yellow wire in a 2001 is the power side of the coil on the relay ( where black is the other side ).
Maybe on the 99 harness it is Yellow is the power side of the coil, and the white / black wire is the ground side of the relay coil ?

In the 2001 EVTM, it shows connecting the Yellow wire on the fog lamp harness to the yellow wire on the headlamp switch ( pin 5 on Connector 246 ), and then the other wire I can only guess is the ground side of the relay coil.

If you want to test it, you can Ohm meter between the Yellow and White / black wires to see what you get. I checked a Bosch Relay, and across the coil got 68 ohms ( using the 200 ohm setting on the meter ).

If you get a low resistance between these 2 color wires, next you can test it another way. Ground the White/black wire to a good ground check that it is a good ground, not all metal items uder the dash are ground, the bracket for the hood latch is not on a 2001. and touch the Yellow to a fused power source, and the fog lamps should illuminate.

I have to try to find a diagram for a 99, to be sure, but it seems like there is not enough wires to do much of anything else with. The directions might be indicating to tied the yellow and white / black wire to wires in the headlamp switch in the directions, like another member had posted ( and this would never work the way Ford said to do it ).

As for running the fog lamps with the parking lamps only, or with the high beams, I have seen several posts on this mod, which explain how to change the switch to allow for it to work with the parking lamps. I don't know if off hand, as I don't have a stock fog lamps harness, they are both PIAA harnesses, with their own switches.

Let me know how this goes, I'll check back tonight.

Sorry for the delay in the reply ( got another I have to do yet ) and good luck with the mod. Let us know how it goes.

 

here is the 99' wiring diagram...hope this helps![IMG]99' wiring diagram[/IMG][IMG]www.f150online.com/forums/images/f150.jpeg[/IMG] [IMG]http://[/IMG]

 

hotrod22,

Could you send me a copy of the wiring information for a '99. I have the wiring harness, valence, and lights. I have not been able to get any information on how to install them. You can email me at "johnson505@qrowireless.net" or "anjohnson@tycoint.com". If you can't email the stuff, let me know on the email and I send you a fax number.

Thanks,
Anthony

 

hotrod22,

The link did not work. I used the quote feature to find where you were storing this at, and it seems to be in a gallery here, but I can't find a gallery with your S/N on it. Profile does not have it in it either.

Can you repost that URL it not showing or just your gallery name.

Thanks

 

i dont know how to attach a photo from my harddrive to my post??? i have the diagram on my computer but cant get it to show up on here. what i did just put that little box with a red x in it , which goes nowhere!?

 

You need to make a gallery, and upload the picture to an album in the gallery. Then when you post, you use the img tags.

The attach a file to a post was disabled due to security holes in pgp.

the URL to get to the create a gallery is :

BTW : did you check the items I noted above with a meter, and if so, were the results with the Yellow and the white / black wire ?

I ran into the same problem as you with my 2000F150. Here is a link from where I had my problem and maybe it will help out on the wiring. Mine worked fine replacing the yellow for the yellow and the white/black for the white/black in my 2000 headlamp switch. It shows it for a 99 in the picture of the install sheet but is also what you swap in your 00 switch.
The ground off the relay caused me a problem with mine but got it fixed with help from here. I just installed my 3rd one this weekend (mine and 2 buddies) and its getting faster and easier each time. Not one of us had the factory wiring already there and my other buddy who doesnt want the kit installed does on his supercrew...

i grounded the white/black wire & made contact with the yellow wire to power(behind the switch, brown wire i think) & in the parking light position the fogs were on , in the headlight position the fogs were on, pulling the fog activation part of the switch out made no difference. i checked with my test light every wire going to the light switch to see if the fog position on the switch interrupted power but none did. the FACTORY yellow wire had no power & there were 1 or 2 grounds(i assume) didnt either(obviuosly) did not mess with the red/black wire(unattatched)that is supposed to go to the dimmer. i dont have a meter, a friend of mine does, i may be able to have him check it this weekend.

 

i tried like you said, to put the scanned image of the wiring diagram in my gallery(just created-no pics yet) but there was an error either the wrong type file or it timed out(im on dial-up...dont laugh). dont know what the prob is?

 

hotrod22

Did you get this worked out yet? Wondering if the link I posted below from my post with this problem helped.

 

hotrod22 ,

Did you get this figured out yet ?

In reading the post prior, when you attached the relay coil to the parking lamp wire, yes the fog lamps would be on when ever the parking lamps are on, aside from the pulling of the fog lamp switch out.

Sounds like it is opertional now, aside from the powering of the relay.

The link posted above from 2000FordStyle, shows that you are to replace the yellow wire in the connector from the headlamp switch with the yellow wire in the fog lamp harness, which should be #5, if I read his post directions correctly. Or I guess you could just T-Tap into the yellow wire from the headlamp switch itself.

Just wanted to find out if you got that far this weekend or not.

 

after getting so frustrated i was almost ready to shoot it, i had to leave it alone for a few days! you know how you can get away from something and you can think more clearly? anyway, i have it wired correctly(according to 4 different people on here) and they dont work. I checked the yellow wire(connected to the switch) with my testlight while pulling out on the **** to see if i had power and i did not! so i am assuming the fog portion of the headlight switch is bad. the parking lights & headlights work but the fogs do not! the yellow wire gets power transferred to it when you pull out the fog ****, right? the problem is none of the 3 dealers in my area stock this switch(if they stocked it, i could test my assumption BEFORE paying $55! for that switch) i was hoping i could find a friend who has a 2000 to 2002(i think) f150 or expy i could try my switch on to check this theory on also, but no luck so far. does it sound like the switch to you guys too?

 

What position do you have the headlamp switch in when you are testing it ?

Unless you mod'd the switch for the parking lamp position, the fogs only work in the headlamp position on low beam if memory serves me correctly.

Just something to look at when testing if they work on not.

It sounds as if it should work. With the headlamp switch in the headlamp position, and you pull out the fog lamp switch, does the fog lamp icon on the switch illuminate ?

 

i am testing it with the brights off, test light on the yellow wire, the parks come on, the headlights come on, the fogs do not, the fog icon does not illuminate. i dont know exactly how the inside of that switch works, but i'm assuming that when you pull out on the **** to turn on the fogs, power is transferred to the yellow(fogs) wire from a hot wire in the same connector, right? has anybody had just the fog part of their headlight switch go bad? is that possible? i guess im going to have to order that switch to find out for sure.
