Need switch on dash power for new buttons.

Any guidance on how to light up new buttons in the truck with dash light power like what lines to tap into ???

 

You have a couple 12v power outlets down low behind shifter, and probably another one in the center console. Any of those are hot with the key on or truck running.

 

You can use the panel fuse for that

also, I use these

Redside Electric Plug-and-Play Switch Illumination Harnesses | Tacoma World

I use the left of steering wheel in the tundra

I also use the ECT (Tacoma tow haul) in my tacoma for switches

 

You should be able to tap into the illumination circuit of a nearby switch that is back-lit. The wires are small so I would recommend using a PosiTap to make the connection.

 

And what color is this wire

 

I don't know what color it may be for your 2020. It is light blue in my 2015. Perhaps @RainMan_PNW can assist with your 2020.

 

Ahh alright thanks for the help man. Love the avatar photo one of my favorite movies

 

It will depend on which switch you are grabbing the illumination circuit from. It varies by switch and by year, and even trim level.

Thank you so much finally for all my stuff looking factory level and lit up properly. Everyone’s assistance is greatly appreciated.

 

You 'da Man, Casey! I knew you would have the info!
