Fog light installation question for '15 Yaris

[NYC-SE]

On the 3rd gen cars the fog light switch is on the stalk for the headlights. The wiring may already reach to where the stalk plugs into the steering column. You may be able to buy a stalk with the fog light switch and simply plug it in. I say MAY. I do not know this for sure in your case but the fact that you said wiring is already present in some spots makes me believe this is a possibility. You would have to get EWD (electrical wiring diagrams) for your specific model to be sure. Or else trace out individual wires from fog lights, relay, etc which would be difficult but not impossible.

On my car there is no fog light switch on the headlight stock. Just the 3 positions (off, parking, on) I have the toyota wiring diagrams for the headlight circuit and it shows the fog light switch on the headlight dimmer switch circuit with a separate button going to the left kick panel beside the dash dimmer switch.
Still no idea.
