  • I have read the instructions for the Crutchfield Wiring Adaptor 70-7554. The document details how to connect the adaptor by matching wires by function, connecting constant and switched power, amplifier turn-on, illumination and speaker channels . I'm ready to answer your questions about the wiring process or other aspects of the device.
  • What should I do before starting the installation?
    How should I match the wires?
    What should I do with unused wires?
    Where should I connect the ground wire?
