fog lights
I have question regarding a 99 f150 xlt supercab, I am putting on auxillary fog lights. I have them mounted on the bumper inside of the little spaces provided next to the bumper, but my only problem is i didnt know how a relay worked , because it came with one, so i said screw that and just routed it so i didnt have to use that and use the fuse instead. so my problem is (finally) trying to get the wire into the cab through the fire wall or whatever, baterry wire and foglight wire the groung inside the cab for the switch i can figure out , but any special ideas thanks

That should be a plug & play system.
Go with the original wiring.
I wouldn't do it any other way!
Stop by a Ford dealership and have someone in service point out the harness that you plug into.
May sure they do it out in the parking lot near the door.If they get you in the shop, It's $$$$
If they won't do that for you for free, ask them for a copy of the schematic.
This is where a good relationship with a dealership is very valuable.

I agree with Dennis. Using the relay is the best way to go. Relays aren't that hard, the manufacter's just make it that way by not printing a scematic on them half the time. If you go to the Tech Articles section and scroll down to the article,"Whiter Whites, Brighter Brights," by Steve Delaney, it will show you how to hook that relay up using the numbers on the relay. Further up, "Headlight Relay System," By Erik Marquez, shows which spade goes where.
Your fog lights will be a lot easier to hook up than headlights. Read it to understand how those relays work. If you still can't figure it out, come back with some questions and someone will help.
If you use your relay, you'll only need a single skinny wire going through your firewall. I've been trying to remember the 99 F150's. I THINK if you look on the firewall between the brake master cylinder and the engine, down low, there's a blank rubber ovel boot, about 2"x 3". This can be used for your wire. If not, take a GOOD look around ths general area, on the firewall and inside the cab, for a place to drill a hole. Make sure to seal it afterwords. Either way thats the easy part.
Because of all the padding and stuff inside the cab, it's hard to push a wire through. Many people use a fish wire to push through, tape the wire on, and pull back though. A coat hanger will work just fine. Fids work really well, too. You push them through the padding and the grommet, then feed your wire in and pull the fid out. To make a fid, find a piece of copper tubing, old brake line, fuel line, whatever. Cut it about 10" long. Cut one end at an angle, so it's sharp. It's done.
It's the little tricks, like relays and fids, that turn an afternoon job into a half hour job.
Good luck..

Howdy, All he is trying to do is hook up the fog lights that he bought,these are the ones that go in the bumper holes.
Ford makes this an option therefore, they will have a simple Plug in and go system ,instead of doing a complete wiring job which is what he mentioned he was trying to do.

Sorry Dennis, I guess I should edit my post to omit:
/I agree with Dennis./
and now:
/so my problem is (finally) trying to get the wire into the cab through the fire wall or whatever, baterry wire and foglight wire the groung inside the cab for the switch i can figure out , but any special ideas thanks /
A few more ideas.
I would go with the relay that came with the fog lights. It's really a matter of personal choice. By adding my own relay to the system, it will increase my flexibility and decrease future problems down the road. If I wanted the option of having my fog lights act independent or come on with my high beams, I could do that. With relays you're only limited by your imagination. If the system ever developed a problem, I always find it easier to troubleshoot something I did myself.
One thing I like to do that I see happen rarely is make the ground side of the relay coil switched. By shunting the main power and one side of the coil and running the ground wire inside the cab to the switch. Only three wires to the relay and if the wire shorts someplace, like through the firewall, lights will come on and I'll know exactly which wire to trace.
Just my .02 cents..
