Tow mirrors 2021

Looking to install tow mirrors. 2021 SR5 sport. I have heated mirrors. Wondering if the turn signal wiring is there from factory?

 

I have a 2014 SR5 that I added tow mirrors to, and the turn signal wiring was there from the factory, just plug and play. The mirrors I got (Boost Auto Parts) also have some back facing white led lights that require additional wiring, that I haven't done yet.

 

@Bmitchell2023 this has been addressed a few times. The harness in your truck will have the turn signal wire already ran, so the new mirrors you put on if wired for the signal should work. I say should, because some folks who have gone with cheap mirrors off Amazon/ebay/etc have had some issues. Normally this is do to the harness pins between the mirrors and the truck having a difference, but once both harnesses line up the signal works. If you go with OEM or Boost, their harnesses match the truck so everything will be plug and play.

Hope all that makes sense, good luck

 

Thanks
