Just get a fog light wiring harness. It includes the relay, switch and all wiring needed. No need to mess with the "smart" box

hole for the aftermarket toggle switch (yuck).
You will be glad you did in the long run and the
OEM fog light on reminder chime will be functional.
Necessary wiring:

+1. Unless you have a Pony Package with fogs already, you wont have what you need for foglights. The extent of the wiring is, there is a location in the underhood fuse box for a relay and fuse, and there are wires run to the headlight switch and SMJ.
A GT headlight switch is a great way to do the switching, but that just provides a ground to the SMJ which is supposed to energize the relay, assuming the relay is in; but most likely, the SMJ is not configured as such and won't ground the relay pin that it is supposed to.
And then there's the need to run the wiring to the lights themselves.
I dont know what wiring kits are available, but I simply got the headlamp connectors and ran the needed wires, tying into the underhood relay/fuse center at the appropriate relay output. And I cheated on the SMJ signal/ground wire, bypassing the SMJ and routing the wire direct to the headlight switch.
It works just like in a GT now, pull out the switch when the parking lights are on, and the fogs come on.

Do you have fog lights at all already on your car? If so, you can just tap into the existing fog light wiring (piggyback) with the GT style fog lights once you get them in.

(The GT headlight sinks the output instead of sourcing it.)
It depends on whick aftermarket fog light harness you get.
They are available on eBay that includes the GT headlight switch
and is properly wired for it AND the fog light indicator (dont forget that...).
I did it and it was super simple. (for me)

I installed a new foglight grill last night using the StreetScene wiring harness and I also bought a GT switch. All went well until it came to wiring the harness into the switch. I don't want the toggle switch supplied with the harness so how can I wire the harness into the GT switch to make it work as described in this thread?
Currently I have the toggle switch which has a yellow wire connected and a red which I would tap into the red/white wire if I was to complete it the way the instructions say with the toggle. If I disconnect the yellow and throw the toggle away, where would I connect the yellow wire to be able to use with the pull-out GT fog switch?
Thanks in advance for any help you can offer.
