    Yes. Lower harness goes to fog lights. Upper is ambient air sensor.

    If you plan on wiring the fogs to a dash switch, just buy a harness for ditch lights. It’s much easier, I’m about to do this with a set of Diode Dynamics on a 2021 SR. I’ll post the process once done. The post above is an awesome write up to use the factoring wiring harness/ECU, but it’s kind of a PITA…thanks Toyota.

    i want to do the same with some diode dynamics. Can you post your process? I planned on purchasing a good harness with relay, connect to battery, and directly to switch in cab. Even though they will turn on with truck off, I will notice and will use them when conditions arise. Please post lots of pics and process :)
