fog light

Ok, I keep having reoccuring problems with my fog lights. At first they were directly wired through the battery using a toggle to turn them on and off. Then after I forgot to turn the switch off and my battery decided I needed to seek a better alternative.

I added a relay and used the ignition switch wire as my trigger for the relay. This would kill the fog lights if I left them on in the chance that I forgot to turn them off manually using the toggle.

I'll be honest, I rarely turn them off as I drive with them on all the time as a safety feature.

HERE is the problem. I have a remote starter, which I use a few tiems a day when it's cold outside. I have noticed on a few occasions that when the car is under remote start control there is a buzzing or crackling noise that is heard through the left front and right rear speaker. I took the car to get it checked out and I was told to just ignore it, it's just noise. This condition only occurs when the car is under remote start control, when you put the key in and deactivate the remote start the buzzing or crackling goes away.

I trusted the persons advice to ignore it and a few days later my fog lights stopped working all together. I looked under the dash and found that the trigger wire that was tapped onto the ignition harness wire was burnt to a crisp. It literally fell apart in my hand.

I took it upon myself to disconnect the trigger wire from the ignition harness, and low and behold the buzzing and crackling noise had stopped.

I have been watching it for a week now and still there is no noise present. I took the car back to the place to show them and they were confused as to why the trigger wire would burn, as they thought it was my Hilow converter I have for my subs, or a bad ground...

They told me that they will correct the fog light circuit and try to figure out how to get around the issue's I'm having.

I've always trusted the advice given here so I'm here asking for some help.

What I would like:

Fogs to turn on and off with key, But without having any draw or issue's when car is under the remote start control.

I was thinking of trying to add them to my headlight switch so that when I turn on the low beams they will come on.

I'm saying low beams because the parking lights are always on when the car is under the remote start control. I'd think if they where hooked into the parking light switch then that would cause the same situation that I had before? I'm not really sure....

Question:

When I use the highbeams will the draw of the fogs affect the wiring or harness as each fog light draws 55W.

HELP!!!!

If the fog lights are hooked up through a relay properly, it will not place a draw on the headlight highbeams.

Foglights are usually wired to low beams only, if you want them to be on with high beam or low beam they will need to be triggered by a circuit that goes to +12volts only with the key in the tumbler. When you remote start a vehicle, it is usually required to power up the same circuits as if the key was in the ignition.

I would recommend that the fog lights be wired to a grounded source, a switch to turn them off if you want to and turn them on when you want to regardless of high / low beam, and a fused relay to make the fog lights operate.

What vehicle is this for?

Find a ground inside of the vehicle. Attach one end of wire there, run the other end of the wire to a switch mounted in the dash. Run another wire from the other side of the switch to a relay in the engine compartment. Attach this wire to pin 86. Connect pins 30 and 85 together and attach to one side of a 15 amp fuse, take the other side of the fuse to +12v at the battery. (mount the relay near the battery). Use pin 87 to connect to both fog lights. Ignore pin 87a. Make sure that any wire coming through the firewall is run through a proper grommet and that all wires are properly protected and not run near anything too hot.

Rob,

by what you are saying, is that I should just wire it up straight to my battery? I already have hte relay setup exactly how you described except the trigger relay for the relay is differnt.

so your advise is to forget about the lowbeams?

Question...

If i'm going straight to the battery for the relay trigger, then that means i'll have to remember to swithc them on and off? Is there any other way i cna warn myself they are on?

I say to wire them off of your parking lights for simplicity.

I've been sick lately, sorry I won't be on much.

If I'm using the parking light circuit won't I still have the smae problem as before with the buzzung and crackling when the car is under remote start control?

If the parking lights are on when the remote starter is running the car, then won't the extra draw from the fog lights cause a problem?

I'm going to try to conenct them to my low beam headlight at the headlight switch...
