I have successfully upgraded my 2014-2020 Toyota 4Runner SR-5 to use TRD Pro mirrors with turn signals and puddle lamp.

This project would not have been possible without the retrofit wiring harness and detailed instructions provided by Tanner, aka Old Red. With his kit, you can upgrade the standard heated mirrors on a 2014-2020 Toyota 4Runner SR-5 to also include the side mirror turn signal and puddle lamp found TRD Pro mirrors. In upgrading my 2019 SR-5, I used aftermarket TRD Pro mirrors with the aftermarket sequential LED turn signals. I've posted the finished results on YouTube. Total project cost was $270 for all three products.
