Fog light wires for 98 Ford f150 xlt 4x4
 

I was looking to install fog light but I am not sure if it is prewired for it. I have the precut holes in the original bumpers and the light switch does pull out when regular light is on. I looked near the area of the fog light hole and saw a connected wire with a white end. Could that be it?

On my 97 I went and bought a fog light switch then tapped in to the brown wires behind the switch to a park light turn on then put the new switch on and hooked everything up I'll try to get a picture in a bit make sure the relays are in the correct spot

Thanks for responding to my question. I asked a bunch of people in the know and they were not sure. 2 said they would have to look at it some say it should others say they don't. I am assuming that you have hooked yours up as you described, is it working without any issue? I would like to see a picture. As I understand it the kit needed to install the wires are no longer available from Ford if I in fact need it. I attached that wire with the white end I was talking about earlier, you know what they are for?

U shouldn't need to tap in to anything. The wire harness should already be there for factory fog lamps. I have an 03 and all I did was get the fog lamps and switch from a junkyard and installed them. While looking for a place to hook up the wires, I found another bunch of wires wrapped up in wire conduit and tape that didn't look right. It looked to be too bulgy for the wires that were coming from it. After unrolling the tape, an unused harness popped out and plugged right in to my fog lamps. I turned on the switch and the lights came on.

when I took the brown wire splice off to fix something it would not come on and I don't know if on the 03 since it's a different switch that it is the only difference

It sounds like I will need to have it looked at. I'll let you guys know what i found out, thank for your input.

I brought it in to a ford dealership cause they said all they would have to do is look under it and see if it had prewires, they tried to jack me for 125.00 just to look. They said probably does but needed to look...... Still no answer. I looked again still nothing . Anyone ?

I'm tellin ya buddy, it is prolly prewired. Ur just gonna have to look. Mine were pretty wrapped up in tape and conduit, u just gotta find where it looks bulky and cut the tape off and pull them down.

This is the wires I had to put together

I must have misunderstood u. I thought u were talking about the actual harnesses that connected to the fog lamps themselves. The harnesses for those were up under the bumper, and were wrapped up. Once unwrapped, they connected directly to the OEM fog lamps I got from the junkyard. As far as the switch, u will need to buy the actual switch that turns and pulls out. All the wiring for ur switch should be there, and u won't need to run any extra wires. Just buy the switch that is equipped to turn on foglamps and they should turn on.

Your truck should have the harness already installed. If not, no biggie. Order a 9005 harness from theretrofitsource.com.

Just tap the harness into your parking lights and they will come on whenever your running lights are on.

I do have a fog light switch

Kmconley thanks for the input. I spent 2 hours looking yesterday for that harness or plug-in piece for the fog light. I looked at the part of the wiring at the headlights where they all meet and pulled/cut the covering like you recommended, but still nothing. I do have the switch that pulls out when on the on position. Should I follow and continue to cut into this bunching of wire covering? How far back should it be? I cut back about 5 inches or so.

98 4x4's, with the bumper with the two holes covered (removable plastic inserts) come prewired for fog lamps. The connector is taped just behind the bumper on the body assy, and plug directly into the bulbs you choose. The headlight switch must be switched out to have one that shows the fog lights and you are good to go. It took me longer to undo the remote oil filter than putting in the lights themselves. Go for it. It is a simple, 30 minute job at the most.

Akdoggie this is what I'm looking at below. Where am I going wrong? That wrapped up bunch of wires in # 4 I already cut open to see if the connector was in there and it wasn't, so I wrapped it up.

It pulled out, as it understand, for the fog light turn on position. Is this the wrong switch? , even if it does pull out?

Ok, your fog light wiring is UNDER the bumper attached to the firewall. It is wrapped a a bundle, and pulls out and hooks up 100%. You are going in thru the headlight which has absolutely nothing to do with the front fog lights.

Here are a couple picts of the right fog light from the backside.

Akdoggie, thanks for posting the photos. I looked in that firewall area where the wires come out from on your photo. This is that grouping of wires in the conduit that I retaped up in my photo's. Still can't find the darn thing.

Ucbro. take a picture from under the bumper behind the fog light panel plate and let's see what we can figure out. (I said firewall when I meant core support). Sorry if I confused anyone. Brain fart at the most inoperative time. lol

UCBRO....look at your photo 3. It is to the square white connector that the fog light harness is plugged. Also the headlight switch in your photos is not the correct one for the fog lamps. You will need the one with the small fog light picture on it. Like below.

Akdoggie, thanks again for walking me through this. I took off the black temporary plate for the fog light placement and took some more photo's. Here you go.

I disconnected the airbag wire and unwrapped the conduit to see if... Nothing

Just for good measure

Your pics 10-12 show the opening where the wiring is suppose to come out on the right side. I do not see the "Y" off connector. Look at my pictures of the right side of my harness and you will see where the "Y" hooks into the harness. I do not see it on yours. Check that second wire loom and see if it is tucked inside the horn a bit. If not, then, I'm sorry to tell you, but it isn't there, and you will have to make up a quick harness to make things work. Hope this helps

What happened to the left front core support? Did someone weld in some metal to replace some rusted area? Where is your truck from? Just curious to amount of road additives in your area.

I deleted the rain prone section that funnels water to the core support and welding in some extra bracing. I'm doing a new enginge setup and thought it was def worth the effort.

I live at about 5000ft above sea level and we see snow about 5 months of the year. Salt liteally kills everything around here. So just taking some extra precautions.

I live near high knob VA. haha we actually had an episode on finding sasquach here.

We used to salt our roads also and had terrible rust back in the 70's and early 80's. We don't have that problem anymore. You will find the 88 and up Chevy's rusting pretty bad, and some of our model trucks rusting, but anymore, no. They've gone to a liquid that seems to be cheaper and works better. We'll see, but at least we don't have the problems we had back then.

We more than get our share of snow, Anchorage AK area, so I can sympathize with you. lol. If you looked at my front pictures, only the damn bumper bar braces have rust on them. Nothing else on this truck has any rust. It's weird how the bars, front and rear are the only place to show any rust. Must be the swirl effect of the wind and road crap that chips the paint and causes the rust. I don't know what else it could be, except cheap metal. Nah. Not on an American vehicle. lol

Akdoggie thanks for your help on this, it was more involved than I thought but as usual cheaper than paying a pro. I am painfully obviously a novice, if I can do it myself I do. Can u provide me a step by step, photo's for dummies, resource to install a harness? Thanks again.

Try this and see if this fits your use. It should work perfectly for you. It may say Toyota but it is basically universal. Power, ground, etc.

You can also use this. It is more simplified and says HID, but it is the same for regular bulbs. Good luck.

Does anyone know if the 98 xlt has the harness with the fog light plug in already in it? Thanks!

That is what this thread is all about. You have to look under your front bumper where we have shown and see if the harness is there. If you have a bumper without the holes for the fogs, it is doubtful. Otherwise it is a tossup.

Alright thanks! Sorry for the dumb question lol

did you guys find 'em? you got my attention now, oh and by the way i have the same problem i have the bumper with fogs but cant find the harness and have the switch that was posted earlier (with out fog light drawing)

None of the trucks without fog lights from the factory come with the correct headlight switch. You have to install the one with the small fog symbol off to the upper right of the rotary knob.

Just look at the extreme right of your front bumper, look underneath, find the horns, then look at the hole in the front core support. It will have at least 2 wire harness come out. The one with the "Y" making it three wires is the harness you need. If you don't have the "Y", then you will need to install a fog light harness of your own or aftermarket.

Just curiosity, does your serial number start with a 2 or a 1? I'm thinking the Canadian models (2) have the harnesses, and US (1), maybe not? Just a thought.

and I have one for sale in the FS section.

well my truck has the bumper with foglights, but not sure if one of the previous owners had it installed or if it came factory, and i couldnt find any wire above the horn (just the ones to the lights i need to check again though. VIN starts with 1

Look at the pictures that I and IDB posted. It shows where the light wires come from and where they plug in.

yeah i know where to find them, but to me it just feels like two wires. but then again i never really get a chance to check every time i start to check something comes up and i dont get a chance to check good

I looked around for a fog light harness and it's all but non-existent. Ford can order it for 150.00 part# 15a211. Ouch! Is there another universal harness I can use or can I just tie into the headlight or turn light?

I put up a quick schematic so you could make your own real easy. It is basically a relay with some wires added to the lights and back to a switch. If you were to get some 16 ga wire and run that, you'd have enough current to pull for the lights without a problem. You can also go on eBay and get a universal wiring harness for the fogs.

Here is one yuo can use. It is a simple kit even if you don't use the lights. You can use them somewhere else or sell the lamps. The harness is decent for the price. Just a thought.

I think I'm just gonna get rid of these fog lights and maybe get some rigid industries lights in there but thanks for your help. By the way I checked and had NO wires and NO relay (where the relay should go)

let me clarify that last statement..... i might get rigid industries style lights cause rigid industries is too damn expensive haha...... who knows maybe ill go with that kit you posted.

Another dumb question. I haven't popped the hood yet but I noticed that my light switch has the fog light switch on it. Does that mean I have the fog light harness?

does your truck have a the valence with fog lights? if so, look through this post and look at where the wires come out of the radiator support. if the truck has the wires they should be tucked away with the other wires, maybe even taped together.

No. I'm wanting to put a fog light bumper on and that's why I'm asking

Either way look at the wires from your headlamp and just look around in that area

Hey akdoggie I confirmed with Ford that my truck does not have the wiring harness and it will require the correct switch with the fog symbol on it. You were correct. I got the lights and looked at that harness you recommend, how long should the wires be? I was thinking 6-8 ft. One guy on eBay said 8 inches but he must have misunderstood my question.

Ok thanks!

We'll I got it done. It was extremely difficult to get that left one in behind that oil filter. A real pain having to move it then getting the screws back in there blind was trying. I plan on putting in a new switch, I will post photo's of the major :) project.

Why didn't you just drop your oil filter and either change it while you were there, or if it's new(er), reinstall it? It makes working on the left fog light so much easier. JMO of course.

Ran the wire through that plugged whole in the firewall
 

The completed work. Thank you akdoggie for walking me through this one. I thought about just unscrewing the filter but I didn't think that would leave enough room. Thanks again.

Closer look at whole in fire wall,ran wire along molding

Is there a reason why you wires an extra switch versus just hooking them up to your running lights so that whenever you lights are on there on?

Wayne

Z7what, I asked around and was told that there was a chance that the power running through, with out a relay, could melt the wiring and/or could dim the lights. I didn't really want the light on every time the main lights were on any way.

Looks good. I love the clear fog lamps. Good job UCB:thumbsup:
