    American Autowire 510243 Details

    The wiring in your Mustang is fifty years old and probably not up to the task anymore. If you need a harness that has both OEM and modern features, this is the one for you. This Classic Update wiring harness from American Autowire allows you to plug into the original gauges and dash accessories, headlights, taillights and heater controls.

    The Classic Update Series Harnesses are recommended for modified original vehicles, not OEM restoration projects. Fits 1970 Ford Mustangs.

    Everything is color-coded and instructions are included - it's a painless process

    2. Original Ford styled headlight switch connector.
    3. Headlight enhancement relays allow for high-powered halogen headlights.
    4. Separate relay controlled circuit for cars that have stock or aftermarket fog or driving lamps
    5. Original Style ignition switch connector
    6. Standard turn signal flasher and hazard flasher mounted on fuse panel; horn relay mounted on harness.
    7. New ATO Fusebox fits the the left of the original bulkhead pass thru opening and allows for easy fuse and circuit breaker accessibility.
    8. Harness allows for most aftermarket accessories such as: gauge packages, heat and air conditioning systems, power windows, etc.

    16. Rear body harness assembly plugs into the main harness behind the left hand kick panel for easy accessibility and allows for original or custom routing.

Fuel tank sender wire and sending unit extension are also included.

    18. Engine wiring includes feeds for coil, tach, water temperature, oil pressure, brake warning (with later updated extension if necessary), and electronic speedometer (if necessary). A heavy gauge alternator feed wire is provided for a typical 1 wire high-powered installation.
