    I installed my power folding mirrors from
    Boost Auto with the help of Phil Gambia’s harness. Very easy pnp setup and was simple to install. Highly recommend!

  • Dan Saltis

    Installed my power folding tow mirrors. Definitely recommend Phil Gambia at Harness Dr. I ordered the PnP harnesses and the mod for the dual functioning running lights and turn signal. I got the harnesses when a week. The install was easy and the instructions with color pictures were great. Great product and great service.


    Just installed my Tow Mirrors Power Folding aftermarket. Went from power folding standard mirrors. Big thanks to Phil Gamboa at Harness Dr for the custom Harnesses. These mirrors needed dual function adapters to make the running light switch between running and the blinker when activated. Smooth install using his Youtube video. Highly recommend.

    Definitely recommend these harnesses to anybody doing the upgrade. Really simplifies the install knowing that you don’t have to do ANY wiring. Simply remove your stock harness and plug this harness in place. Virtually impossible to tell that the harness has been modified, looks exactly like it would if it came from GM.

    I highly recommend these harnesses for anyone doing a tow mirror swap on a half ton pickup. I just finished installing these into my pickup and I’m very happy with it. Everything is easy and straight forward just plug and play 👍🏻👍🏻
