    Classic Update Kits give you one of the most complete kits on the market to “Make Wiring THAT Easy”. They are designed for specific year, make, and model configurations. The 1970-1972 Monte Carlo Kit is no exception. The kit boasts 19 features making it the most complete system of its type in the industry including:

    • A replacement headlight switch with internal 30amp circuit breaker, retention collar nut, adjustable length shaft, and custom knob.
    • Standard turn signal and hazard flashers are mounted on fuse panel. A new horn relay is mounted on the main dash harness.
    • Fuse box designed to fit in original location. All required hardware supplied. New ATO fuse panel allows for easy fuse and circuit breaker accessibility. Harness is laid out and formed to allow for nearly all after market accessories such as; gauge packages, wiper systems, heat and air conditioning systems, etc.
    • Original switch connector bodies – an American Autowire exclusive feature
    • Steering column connectors can plug directly into most aftermarket steering columns or stock 1970-72 GM columns that use stock GM turn signal switches.
    • Separate under dash courtesy lamps for use along with your original dome/interior lighting.
    • Instrument Cluster wiring is designed with a “cluster harness disconnect” system for easy service and assembly. Original terminals and connectors (another American Autowire exclusive) are provided for stock cluster connections. The system will also connect into most popular aftermarket gauges such as AUTOMETER, CLASSIC INSTRUMENTS, DAKOTA DIGITAL, STEWART WARNER, VDO and others.
    • Rear body harness assembly plugs into the main harness in the stock location and our longer leads allow for stock or custom routing of the wires. Rear body wiring includes backup light lead wires with correct lamp sockets, stop and tail light lead wires with correct lamp sockets, terminals to mate with the license plate connection wire, side marker lead and ground wires with lamp sockets, and fuel tank sender wire with trunk grommet and tank connection.
    • New floor dimmer switch is provided for ease of installation. Wire length and connection accommodate original floor mount dimmer switch.
    • GM bulkhead connectors for the engine and front light wiring are included (another American Autowire exclusive) and allow for easy installation with original or custom routing.
    • Engine wiring includes connectors for original points type as well as H.E.I. distributors. Power and tach connectors supplied for GM H.E.I. distributors. Alternator connectors are supplied for GM “SI” series internally regulated alternators. GM “CS” series alternator adapter is available separately.
    • Front lighting includes extra long leads that can be routed for stock or optional appearances. All headlight, parking and directional light connectors (lamp socket pigtails are also provided for 1971 and 1972 applications) and terminals are provided along with a switched trigger wire for an electric fan relay (usually recommended with AC).
    • Monte Carlo only rear tail lamp extension harnesses with grommets and lamp sockets.
    • Original style light sockets, switch body connectors, terminals, etc. packed into every aspect of this harness help make it the most complete system of its type in the industry!


    Please note: Classic Update Kits do not support Ammeters



    Validate the kit contents with the component list included on page

    2 of this sheet before proceeding. This kit is intended to be used in

    a modified vehicle. Please read this sheet thoroughly and be sure

    that you understand everything explained on it prior to opening any

    of the enclosed packages, or before attempting to install any of the

    components. Once this kit has been opened or a component

    installed, the kit is not returnable.

    1. This kit should typically be used in a

    MODIFIED application only.

    2. This kit supports the use of factory heater systems and aftermarket heater and A/C systems. The kit supplies power to a factory A/C control head but


    include the actual A/C harness for an original factory A/C vehicle. Factory original A/C harnesses are available under our Factory Fit product line as they are self

    contained harnesses made to fit and work with the stock A/C component configuration.

    3. This kit supports the use of a high current self-exciting 1-wire alternator or other style internally regulated alternators. An adapter may be necessary in some

    applications. The use of a stock, low amperage alternator is seriously discouraged as they cannot handle the higher current requirements of updated ignition

    systems, electric fans, aftermarket A/C systems, stereo systems, air ride suspensions, and other power hungry accessories and will ultimately create performance

    issues with the system.

    4. This kit

    WILL NOT support the use of a factory ammeter. All AAW kits are engineered to supply the optimum charge to the battery. To achieve this performance,

    we route our 8ga. charge wire directly from the alternator output charge terminal to the starter battery termial. Due to the path of the charge being altered from the

    stock configuration, the gauge can no longer see a charge vs. a discharge, so it will not work properly. When ammeters were originally used, most generator or

    alternator current outputs were rated at a maximum of about 25-60 amps. Modified cars being built today typically utilize a 100 amp or higher output alternator.

    With these higher current units, ammeters, generally speaking, become a safety hazard. Ammeters are usually wired in parallel to the charging circuit, are

    typically unfused, and can short very easily causing a fire. A voltmeter is recommended as a good alternative.

    5. This kit

    IS NOT set up with a resistance wire for a standard, points type ignition system. It is wired with a full 12 volt primary ignition feed that is hot in the run

    position. Primary ignition voltage in the starting position is handled via a full 12 volt bypass wire. Our system will support HEI, MSD, other electronic ignition

    systems, as well as most all computerized Fuel Injection systems. If you wish to run a points type system, there are illustrations on the engine connection pages to

    do so. Extra parts (ballist resistor) that are not included in this kit will be required to complete that operation
