Adding Fog Lights on Tundras without them

Hey everyone I have a 2018 tundra sr and went through this thread and everything is helpful except I don’t want to replace the headlight stalk cause my factory one has auto and no drl and would rather get a factory switch that goes in the dash. Has anyone done it this way? I already purchased the relay and just need to find the female adapter for the factory harness for the new lights.

 

Yes that can be done by adding an ON/OFF switch that will ground your fog light relay. The foglight relay has 4 prongs. Bend the prong (the one that is negative) up so you can connect a wire to that prong. Run that wire to your ON/OFF switch and run another wire from body ground to switch. With this set up, foglight will stay on after you take the key out. So you must remember to turn the switch off.

 

You can get these switches that will replace the blank panel that you are pointing to.

Can you tell me which one is negative?

 

Greetings to everyone. Has anyone traced the fog lamp wires into the fuse box? I bought everything but never checked for relay receptacle inside the fuse box. My truck is prewired for fog lamps but not relay receptacle inside the fuse box.

 

Amazon delivered my new lever/switch today.
Can't wait until the sun goes down to blind oncoming drivers with my new fog lights!!!

 

I have a 2021 SR, with automatic headlights, but no fog lights. Is there a way to wire new fog lights to the same switch relay as the automatics? And I'd like to install a rocker to turn them on/off regardless of the automatic headlights.

Thanks!

 

I was getting ready to do this but it appears the slot where the relay goes doesn’t have any metal contacts in it? The relay just sits and and pulls out. Ran out of sunlight so didn’t get to look at it in depth, but am I missing something here to complete this?

 

I bypassed the fuse box and just direct wired an external relay when adding the Fogs to my SR. Certainly would've been nice to use the wiring already in place but have not taken time to go back and look further as I also noted the contacts are not included to the SR fuse box.
