This guide provides instructions for installing the Toyota Dual Radio Plug.

When you receive our kit, you'll find a dual radio plug adapter included. This component is designed to enhance radio reception in our head unit. While in the future, all our harnesses will come equipped with the dual one, if what you have in our cable harness is a single one, follow these instructions for optimal performance.

Verify Compatibility:

Before proceeding, ensure that the Toyota Dual Radio Plug is compatible with your vehicle's factory radio. If uncertain, check the factory radio plug or reach out to us for assistance.

Preparation:

  2. Locate the blue wire from the radio plug of our harness.

  3. Cut the blue wire.

  4. Connect the blue wire from the dual one to the cut end of the old blue wire you just cut.
