I have a 2003 XL and I bought some oem fog lights and I am getting the radio bezel with the switch what else do I need to complete the project.
I also allready have the fog light connectors by the bumper.

 

You probably already have the connector inside the dash as well. You MAY need the relays that go in the relay box in the engine compartment. What some have found is that the connector they need was already in the dash, just like they are already down under the bumper. However, sometimes the relays (and maybe the fuses) are missing.

Your owners manual shows the layout and which relays are for the foglights. You can look now to see if they are there or not.

 

This may sound lke a dumb question but I am not very good with electronics what does the relay look like and where would it be if there is one?

 

In the engine compartment, in the junction/fuse box. Look in your owners manual to start and then "explore", lol. I don't have any pictures handy. Usually in the engine compartment, on the firewall, on the drivers side. The box is about a foot long and has a lid that snaps off.

Relays are generally little white or black "blocks" with terminals coming out one end that plug into sockets in the box. They are generally from an inch to inch and half long, and vary in width from about 1/2 inch to an inch.

 

There is a good diagram of the 3.0L Power Distribution Box on page 159 of your 03 Owner's Manual. Fuse 31 and relay numbers 48A and 48B are specific to the foglamps.

If your XL has a 2.3L, the Power Distribution Box (page 156) is wired differently and does not have a provision for fog lamps. In that case, the simplest solution may be to include the foglamps, switch, fuse and relays in a fabricated subharness.

 

ok, I just looked in my manual and didnt see anything about the wiring. Anyone have any links to a good way to wire up the factory foglights off and Edge to an XLT. heck, if i could make them come on with the head lights, I dont mind, but someone at Ford told me if I splice them into my running lights or head lights, I could fry the wires. I just want to make sure they are safe. I would prefer they shut off when I turn on my head lights, but Im not too picky. BTW, I know nothing about wiring, so talk to me like you would tell a 5 year old.
