    This will need to be your go-to harness on the Gen3 Escape. It worked very well and seems to be of good quality. I’m very happy with how much more simple this made my swap.

    Still waiting on further assistance with my upgrade. Awesome work with creating a harness and program for this upgrade. Just about Every Ford forum and even Ford themselves say this upgrade isn’t possible. AVOID the nay sayers.

Hi everyone,

Our 4″ to 8″ Sync 2 and Sync 3 harnesses are currently out of stock — and due to the newly announced 145% tariffs on Chinese imports by President Trump, we won’t be able to restock them for the foreseeable future.

For the past couple of years, these harnesses have been made in small batches of 100 through a vetted overseas factory, as U.S. manufacturers require much larger order quantities, and have much higher prices than we can realistically support. Even at $229 with free shipping, free programming files, and lifetime support, our margins have been thin on these harnesses.

With the added cost of tariffs, continuing production is no longer sustainable.

We’re exploring new options outside of China and hoping this is temporary, but for now, this product will remain unavailable. Other products on our site will remain available as they are sourced from the US.

Thank you for your understanding and support.
