Help with factory switches for light bar

I have a 2024 Tundra SR5 TRD. There are blanks on the switch panel at the left side of steering wheel. There’s a full wiring harness which connects to both the switches and most of the blanks. The blanks are for options I don’t have like 120v inverter, led light bar, heated steering wheel etc. I’m wanting to buy a factory switch for led light bar for use with my light bar. I can connect the switch to the led light bar connector on the harness (currently on a blank). But where under the hood can I then connect my lights? I’m assuming the switch tells the ECM to turn on a relay in the fuse box but not sure. Anyone know?

 

Welcome to the club, the pros will chime in shortly.
You could try using the search function too but can be hit or miss at times.

 

You wont be able to use the OEM Pro light bar switch. You’ll have to get an aftermarket one.

Here are some very clear instructions from Baja, which I’m sure is universal for installing. I used this switch, and it was a perfect fit. There are others on the market that work too. With regards to the relay, your bar should come with a harness that has a relay, otherwise you’ll need to purchase one.

This is a great video if you need info on the switch connection.

 

you absolutely can use the factory switch, just requires a good amount of work. See thread here
