Yes, after the mod, turn on your parking lights. 8)

I'm not sure, havent really looked into it very far, however here is some insight from a previous post of mine:

The good thing, you can connect the DRL wires to the halo wires without any diodes, and each will power the other on.
Halo's on with DRL, DRL on with halo's (and therefore park lights, headlights)

Great writeup, thanks for sharing!

lets hope i didnt just burn my dollaz!!

x2, after doing this is it still possible to have just the halo's on?

Just an idea to save the time to remove the front fascia. Why not insert a fuse (with a tap) in the place of one HID fuse and in place of the "FOG" lamp fuse. Put the tap on the load side of each fuse and then connect the taps with a diode. The fogs would be on normally and also on with the headlights.

Ok.. I got the non RS version... has the exact same connecting pins...

Swapped it out with my light switch... auto on auto off works... halos work... xenons work...

fog lights... don't work!! sorry guys... looks like the direct swap is a no go... :(

will check in the morning if the DRL's come on... then try pushing the button just to see what happens...

I'm sure someone will come up with a plug-n-play solution soon.

GM...halos should be DRLs....give us back our fog lights for the RS cars.

do i need to place 12volt Zener Diode on each fog lights wires

I have shrunk the pictures, if you want the original large ones, let me know.

It does require stripping and splicing wires to the factory wiring harness in the front bumper.

This is my idea, and it may or may not be perfect, if you see improvment areas, be my guest. I've run with this for 3 days now, with no problems.
Yet, as always, perform and use at your own risk.
The way I wired it, you can easily disconnect the whole harness if something happens, without ruining the main vehicle harness.

Parts required:
Two (2) 12volt Zener Diode (I got from radio shack for $1.50) (Pic 1)
Solder
Electrical Tape


1. Remove the front bumper (there are other threads with instructions)
2. Locate the wiring harness connector you had to disconnect to remove the bumper, above the right DRL. (Pic 2)
3. Pull the connector out of its tab, and pull it enough out of the bumper to work with. Unwrap the electrical tape. (Pic 3)
4. Cut slits and then strip the outer wire coating, being carefull not to cut the actual wire.
Do this to the purple, brown, light blue, and dark blue wires. I made my first slits all in a row. (Pic 3)
5. Then strip towards the bumper on the purple and brown wires, enough to solder one end of the diode in. Then strip towards you, on the two blue wires.
6. Using the beautiful wiring diagram I scribbled in the field, (Pic 4), install the diodes in place.
The direction of the diode is critical. If you notice, on one end of the diode, there is a black bar.
As in the wiring diagram, in the right upper corner, power flows from blank to bar. It does not flow the other way.
7. Connect and wrap the blank end of the diode around the purple wire, pointing towards you (Pic 5)
8. Solder the diode into place (Pic 6)
9. Wrap the soldered end with electrical tape, ensuring all exposed wire and diode is wrapped. (Pic 7)
10. Connect and wrap the other end of the diode around the exposed light blue wire. (Pic 7)
11. Solder diode on (Pic 8) and tape it up too (Pic 9)
12. Now straighten the two wires and your new diode out, and tape it together (Pic 10)
13. Now do the same thing to the brown and dark blue wires.
Ensuring the blank diode end is on the brown wire(Pics 11-15)
14. Now tape all wires up together, just as it was from the factory (Pic 16)
15. Now place the connector and wiring harness back in place, it their tabs, just as it was from the factory. (Pic 17)
16. Now reinstall the bumper

And walla!! If done correctly, your driving lights will come on as they normally did, and when you turn your park lights, headlights, or even high beams on, your new fog lights will also turn on!

If you follow the DIY it is for both DRL's. You should have striped back 4 wires and soldered on 2 zener diodes.

Purple & light blue wire should have 1 zener - this is for one DRL

Brown & dark blue wire should have 1 zener - this is for the other DRL

Thats one of the first things I tried. Those "Fog" fuse holes do nothing. I've fed power into them, and they dont do anything.

Hmm, that kinda sucks. Thanks for checking for us though! Sorry you had to spend the money on it...

thebrainhart... i left the RS switch on my SS since everything works (except fog switch).... plus it looks so much better and its as if it was meant to be!!!!
