Mustang fog lights

Are these going to be "fog lights" for use in fog, or just additional lights? I have not seen a small "slit light" that is worth anything as a real "fog light" OR a "driving light"

I've not actually decided on the actual light package yet. But I have seen some pretty powerful 'slit lights' but they were pricey. If I go for 'fog', I'd probably put them as low as I can. But the switch and wiring issues are still the same.

Law limits you to 4 projecting beams at a time, so if your car has high and low beam lamps that light together for high beam, the car needs to be wired to prevent the aux lighting from coming on on high beam - for fog light use that is a functional requirement as well as a legal one. Also it is illegal to drive with Fogs only - so they should also be wired to NOT come on without the low beam headlights.

For "long range" lighting with 4 bulb headlamps, you would need to shut off the low-beam bulbs when you turn on your long-rangers.

Uh, did you read my original post?

Ideally you want the factory wiring harness if they are going to be "fog lights" It is designed to do do it right. I don't know if the Mustang is pre-wired. The Chrysler PT cruiser is. The Ford Contour/Mystique was also pre-wired - at least on some models. All that was required was the upgraded switch, the lights, and installing a fuse and relay.

In MOST cases it is strictly relay logic - built into the relay/fuse block so if not pre-wired on a car where the lights are available as a factory installed option, the add-on kit is a plug-in harness, relay, and switch.

Uh, exactly. That's what I was asking. What is in the kit.

My Intrepid, for example was 99% there. I replaced the lowed rubber of the bumper that came from a junkyard, plugged in the lights, and put in a new dash switch. That was it.

Ford HAD a kit. But I don't know what was in it.

THAT'S WHY I WAS ASKING!!!

At least in one case an aftermarket kit seemed to include an original Ford light switch, but for the wire harness you 'vampire' onto two wires and have to drill the firewall into the engine compartment, then mount relay(s).

In other aspects it seems that Ford leaves the wire harness in the vehicle. I thought at least it might come to the light logic block, but I'm not sure if that is in the engine compartment or behind the firewall. THAT'S WHY I WAS ASKING!!!

Get a manual or ask the dealer parts department. That's what they are for - and VERY often the parts are cheaper from the dealer than you can get them from a third party - even on-line.

As an example, the speed sensor for the left front of my '96 Ranger is less than 1/3 the price from the dealer as from NAPA On-Line.

Cheaper?? That's quite surprising!

On the other hand, I've seen some suspension parts for my Mustang that from Ford came in three 'flavors' as to street to full race. But the aftermarket only came in one flavor, so I wonder which one it was.

Usually I hit the salvage yard. Like I did for my Intrepid. I found a dash for my 85 Jeep Wagoneer with full instrumentation. $20 and it dropped right in, and now I had full instruments with tach. All I had to change was the oil pressure sensor from a 'switch' to analog sending unit. Pretty simple. I even managed to move the odometer without triggering the tamper pad so I kept my original mileage. (Had to do a few other minor tricks, but it was actually pretty simple) For my 99 Cherokee I found the switch bar, but turns out the wiring went to the firewall, but no further. There wasn't any wiring in the engine compartment for the fogs, so I need to finish that up. But, I found that everything was there in terms of wiring for adding factory cruise except the clock spring. Swapped the clock spring, dropped in steering wheel switches (but the manuals are all wrong, you have to be careful, but only about the switches) and the servo. Once I figured out the issue with the switches, I had the cruise working fine.

I'm not familiar with the local Ford dealer for parts... Long story, and it involves an ownership change...

Introduce yourself. When I was a service manager (not ford) I helped a lot of owners figure out what they needed to do. Helps if you buy parts from the dealer - and get the occaisional service work done.

I kinda agree. I had a running light kit installed in my Escape by the dealer. It was a Ford product, made for the Canadian market, and it works perfectly. That said, I'm not thrilled with the way it was installed, tying the wires behind the headlights and forcing me to cut the ties if I have to change a bulb.

I must say I have an excellent rapport with my Ford dealer and find their prices to be inline with independents on just about everything. And, even though I was not happy with that wiring job, it does work and they do know the cars.

For what you want I would be thinking billet grill with some small mods. And, I would be surprised if your car does not have a "standard" wiring harness that covers all models. It's cheaper to make one harness for all models and just use the plugs you need. If you get decent fog lights I would have them come on with the headlights as they do an excellent job of adding supplemental lighting even when the weather is good.

The kits I've been able to look at so far use the factory switch in the dash, and then they 'tap into the wires and you drill through the firewall. As far as I can tell, they turn on with the parking lights, and don't care about the hi/lo beams.

What got me was the kits all seem to 'tap' into the wiring behind the switch, and not into anything in the engine compartment. Seems Ford put all the wiring in the dash, but not firewall forward. There was a Ford option kit for the 2006, but I haven't been able to find what was actually in it. Would be really nice if it was a wire from the lights to the power box and the rest was in there.
