• 1970-1974 Plymouth Cuda

Please note: Classic Update Kits do not support Ammeters

The Classic Update Series is a complete wiring system in a box! That means it includes everything you need to modernize your classic vehicle: Headlight, Dimmer, and Ignition switches; Boots, Tubes, and Grommets; Fuses, Relays, and Flashers; Original Connectors, Terminals, and Disconnects.

• Kit Features:
• Standard turn signal and hazard flashers are mounted on fuse panel. A new horn relay is mounted on the main dash harness.
  
  
• 8 Circuit Fuse box designed to fit in original location with mods to the firewall, template included. All required hardware supplied. New ATO fuse panelallows 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.
  
  
• ost Original switch connector bodies (see above for list of items not included) - an American Autowire exclusive feature
  
  
• Steering column connectors can plug directly into most aftermarket steering columns or stock 1970-74 Mopar columns by using the included adapter.
  
  
• 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, 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 or connectors, stop and tail light lead wires with correct lamp sockets, dome light harness, terminals, connectors and lamp sockets to mate with the license plate lamp, 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.
  
  
• ulkhead 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 distributors, OEM Chrysler style starter relay connections, tach and ignition leads, etc. High-powered 1-wire alternator connections are supplied.
  
  
• Front lighting includes extra long leads that can be routed for stock or optional appearances. All headlight, parking light and directional light connectors and terminals are provided along with a switched trigger wire for an electric fan relay (usually recommended with AC).
  
  
• Original style light sockets, switch body connectors, terminals, etc. (where available, see above for switches not included)
  
  
• This kit should typically be used in a MODIFIED application only. This kit does not contain any wiring for, nor will it support the use of some of the more obscure factory options such as the overhead reading or map lamp, time delay relay, overhead console, or door ajar lighting. There are no headlamp, dash panel dimmer, or ignition switches included with this kit. You will need to retain and re-use your originals, or locate replacements if your originals are missing. The original OEM dash harness wiring for any of the factory equipped A/C cars varied from year to year. None of that wiring is included with this kit, and therefore, this kit WILL NOT support the use of any Factory installed A/C set up. However, this kit will support the use of, and does contain all of the necessary wiring for a factory heater system. It also supplies power for any aftermarket A/C or heat system. The factory dash lighting was done through a separate stand-alone indirect lighting harness that snapped into the shroud above the overhang of the dash cluster assembly and illuminated the face of the dash cluster by shining down on it. The lamp sockets for this harness are very unique and are not commercially available. As with the factory set up, this harness is a separate unit that it IS NOT included as part of the dash harness, and will need to be re-used. Your original, factory stand-alone dash lighting harness will plug into the AAW dash harness "dash lighting candelabra" just exactly as it plugged into your original OEM dash harness "dash lighting candelabra". You will also need to re-use your original starter relay or purchase a new one from AAW (P/N 500007, see our other items).
  
  
• This kit only supports the use of a higher current self-exciting 1-wire alternator. An adapter will be necessary for any other 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.
  
  
• 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 terminal. 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 un-fused, and can short very easily causing a fire. A voltmeter is recommended as a good alternative.
  
  
• 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.

The early GM/FORD generators and externally regulated alternators are just not up to the task of providing power to an expanded wiring system like these classic update kits. The point of this kind of kit is really to allow people a way to upgrade and expand their wiring system and so an alternator upgrade is usually part and parcel to this kind of upgrade.

NOTE: These kits are recommended for MODIFIED original vehicles, not OEM restoration projects.

Note: This wiring is designed to work on Internally regulated alternator and have a 12v feed for the coil/distributor/ignition box. 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 both the start and run positions. It will support HEI, MSD, other electronic ignition systems, as well as computerized Fuel Injec- tion systems. If you wish to run a points type system, there are illustrations on the engine connection pages to do so. Extra parts that are not included in this kit will be required to complete that operation.
