Hello,

Because the orchestration of the fog lights and high beams is done by the MICU (Multiplex Integrated Control Unit) the only "simple" way to accomplish what you are after is to ground the PINK wire between F21 of the Under Dash Fuse Box (UDFB) and terminal P3 of the fog light relay with a switch (the switch should be rated for at least 3A/12VDC) to ground anytime you want to fog light ON period (with this switch OFF, fog light operation would return to normal).

Bear in mind since the fog light relay is HOT at all times, the fog light will remain ON anytime your by-pass switch is ON.

I hope this helps,

Cheers!

Hey this is great info! I’ve been searching for this for over a year. So just to make sure, from the picture below, is my understanding to bypass the pink wire coming from the fog lights relay, is that correct?

I’m sorry to bother you... I just don’t want to screw it up.In this case your recommendation is to use a "switch" to do the "bypass", otherwise could I just splice the pink wire to a ground in the chassis? Once again, thank you very much for your assistance on this matter.

Yes, a switch to ground rated at 3A, 12VDC will be adequate. Just remember, by doing this, if you walk away from the car with the switch ON, the fog lights will remain ON as well and you will drain the battery. See attached.

Cheers!

Reviving this; looking for opinions if this is logical.
So in reality if I wanted to use fogs for DRLs, but have full functionality of them when head lights are on;
I could do this by installing a default closed relay across the wiring to the headlight switch, and a default open relay across the wiring to an 12 volt switched connection (lighter socket is a good example).
I wonder what it's like to find an ignition switched 12v source under the kick plate, and also what it's like to find the wiring to the headlight switch.
