Fog light question

[big lo]

I was wondering, can the stock foglights stay on, when using the the Hi beams? Is their a way I can have them on when the headlights are off? I ask this question because to day I will be doing a retrofit on the headlights and putting the halo wires to the parking light, it would look better to have the fogs on with the halos. My problem is since my car came with the stock fogs the wires dont allow you to run with them on, only when you turn on the headlights. Wondering can I splice the wires to the parking lights to have it functioning, plus the fogs are HID so I dont want to over charge the wires, can anyone help me with this pickle? Holla at me please.

If you have the OEM ones where you have the fog light switch as part of the headlight stalk then do the following to allow them to come one with either the high or low beams:

Take the wire that is in pin 4 of the headlight stalk (it will be orange, beige or white, depending on year and if you have DRLs) and cut it (leave yourself some room on either side of the cut to be able to work with the wire.

Take the harness side of the cut wire and cap it off.

Take the connector side of the wire and tap it to the white wire in pin 13.

Are you still using the projector fogs? If you are, remove the factory foglight harness and use the one that comes with the kit. You should be able to turn them on/off whenever you want.

Thanks for the info, just to let you know my is the 2007 sedan S class. Now as for the harness thats located to the fuse box correct? The colors that are here is red, green, light green and two that are spaced with green and grey, so run that by me again please.

The connector pictured above is under the lower steering column cover on the left side, right at the base of the headlight switch.

Good looking Brian, your info will be sorted out as well, just need that extra push. Holla at me. I will post the out come tonight, after all has been done.

Good looking out CT that was very helpful, like I said I will post up the out come tonight, thanks you & Brian for being so supportive to my project. Holla at your boy.

is there any way to get the OEM foglights to turn on by themselves without the headlights?

[IllusionX]

CTScott: what does pin 13 do?

Yes - Instead of of connecting the wire from pin 4 to pin 13, connect it to pin 11 (which is a white wire with a black stripe). Then, it will turn on with or without the headlights.

Pin 13 is the feed to the relay coil for the taillights. It gets switched to ground when the headlight stalk is in any mode except off.

CT thats what I want to do. I want to be able to turn on the fogs when I want should I follow this quote and forget what you had sent to me? Holla my dude.

Yes. To make it easier for tapping the wires together (so you are tapping same sized wires together), connect the wire from pin 4 to pin 7 (the smaller white wire with a black stripe, 3rd from the right in the picture above).

Ok, with this then I will be able to turn on & off from the stalk switch correct? And thanxs again my dude.

Yes. But, with this wiring change you will be able to turn on the fogs without turning on the headlights.

Alright, I tried that option, and the HID was making noise, and the plug wasnt plug in so I put back the wire the way it was, maybe I connected the wrong wire, but you said the the third wire to the right (white with a black line), I heard that noise and just put back the wire. If you have a option that I can run with holla, and if possible with a pic of the harness with plug and the right wire to use. Please hit me up when you can thanxs.

The plug definitely needs to be plugged in, other wise things are floating, and that might be why your HIDs were clicking. the connection point is the 3rd from the right.

So should I disconnect the HID from the fogs, try what you wrote again when finished then connect them again? And yeah they were clicking, I was worried about that, and put the wires back the way they were. Holla at me CT.

Can you snap a picture of how your HIDs are connected to the fogs?

Thanks for all of the info, so just to clarify...I should connect the wire from pin 4 to pin 7 and NOT pin 11 like in the earlier post? I have HIDs in my foglights as well. The kit that I used has a connector on the relay harness that plugs into one of the foglight plugs that the bulb normally plugs into (doesn't matter which) and then power is tapped from the battery with a ground wire connected. The HID bulbs are connected tot he ballasts which are connected to the relay harness. I hope that wasn't too confusing lol.

OK - That gives me a bit more of a picture. The kit is taking the stock fog light feed and uses it to drive the coil of a relay. The contacts of that relay then switch battery power to the fogs.

Either 7 or 11 should work. They are both grounds. The reason I recommended 11 over 7 is that the wire is the same gauge as 4, so tap splicing is easier.

Well I tried and the plug was connected and the HIDs were clicking, my option and Brians as well, is to use the cables set to the the projector fogs, it is very easy to install and it has a switch for the function, I really wanted to use the stalk switch but this what I need to do. With this I can turn on the fogs when I want with no hassle, thanxs CT and thanxs brian, I told you that I would use you option or opinion. Thanks to all. Holla at your boy.

If you can snap some pictures of how the HID fogs are wired in and scan any wiring diagram that came with them, we can figure out how to make them work with the OEM stalk.

[big lo]

Just so that you know CT, I had already started the wiring to the fogs, since I brought the projectors from Garm, meaning the fogs & the retrofit I wanted that look, you know, halos on top and the fogs at the same time, but with the stock wires we all know that cant be done that way, unless you modify it. Now the way I have it connected, and sorry I cant take pics at this moment, is from the stock wires, I had to eliminate the stock H11 plug to accomadate the H3 HID, I also had the HID for the H11 and with no problems, but since I wanted the the fogs when I want them going on with the parking lights. But with the projector kit you can tap into that wire to a relay and a switch that is apart, if I can try some else to keep the function with the stalk, well I m all eyes (ha ha ha). Hello we are writing here let me know I owe you the pics. Holla at your boy.

[heeroyuy01195]

Not to bring back an old thread but I just wanted to say thanks to CTScott, just finished splicing the wires and it worked like a charm!

Its an oldie but a goodie, lol
