The American Autowire harness installation is a project requiring patience and meticulous planning. The process, as documented by a user completing a rewire of a 1974 Cuda, can take approximately 6-7 days when approached with a focus on detail and adherence to provided instructions and supplemental resources. The installation utilizes a 1-wire alternator and necessitates certain component modifications or additions, such as a voltmeter conversion for vehicles with factory-style gauges. Preservation of the original wiring harness is also recommended for reuse of specific connectors.
Installation Timeline and Preparation
The installation of an American Autowire harness is not a rapid undertaking. One user reported dedicating 6-7 days to the project, emphasizing the importance of a deliberate and thorough approach. This timeframe reflects a first-time major wiring project, suggesting that experienced users may complete the installation more quickly. Prior to commencing the installation, careful planning is essential, encompassing the routing of wires, crimping procedures, and mounting locations. The user’s experience highlights the value of double-checking instructions, consulting forums, and referencing available manuals throughout the process.
Required Tools and Components
Specific tools are recommended to facilitate a successful installation. The crimpers sold by American Autowire are identified as being “worth every penny” for the project, indicating their importance in creating secure and reliable connections. Beyond the harness itself and appropriate crimping tools, additional components may be required depending on the vehicle’s existing instrumentation.
Gauge Cluster Modifications: Ammeter to Voltmeter Conversion
The American Autowire kit does not incorporate an ammeter. Therefore, if the vehicle is equipped with factory-style gauges and the user desires an instrument in the original ammeter location, a voltmeter conversion is necessary. Two models are specifically noted as compatible with the gauge cluster: the Bosch FST7985 and the SunPro 7985. Both of these models feature a needle base positioned at the top of the gauge, which is crucial for proper fitment within the cluster. The conversion process involves removing the gauge from its original pod and utilizing only the gauge itself. Minor adjustments to the new voltmeter may be required to ensure a secure and aesthetically pleasing fit.
Preservation of Original Wiring Harness
It is advisable to retain the original wiring harness throughout the installation process. Certain connectors from the original harness are required for compatibility with existing vehicle systems. These connectors include those for the turn signals, ignition, side marker/turn signal lights, and potentially the wiper switch. Saving the original harness until the installation is complete ensures that these necessary connectors are readily available, preventing delays or complications.
Attention to Detail and Color Coding
Meticulous attention to detail is paramount during the installation. When matching the new harness to the original harness, careful consideration must be given to wire colors and connector positioning. The American Autowire documentation provides a color-coded guide to facilitate continuity between the old and new harnesses. Incorrectly re-pinning connectors can lead to significant issues, underscoring the importance of verifying connections before finalizing them.
Additional Considerations During Installation
Several additional tasks can be efficiently addressed during the installation process, particularly when the dashboard is disassembled. One such task is the conversion of the vehicle’s clock to a quartz movement. Numerous online resources provide instructions for this conversion, making it a convenient addition to the overall project.
Alternator Type
The American Autowire kit is designed for use with a 1-wire alternator. This specification is important to confirm when selecting or preparing the vehicle’s charging system.
Conclusion
The installation of an American Autowire harness is a substantial undertaking that requires careful planning, attention to detail, and the appropriate tools. The process involves modifications to the gauge cluster, specifically the conversion from an ammeter to a voltmeter if factory-style gauges are desired. Preservation of the original wiring harness is recommended for reuse of specific connectors. By following the provided instructions, consulting available resources, and prioritizing accuracy, users can successfully complete the installation and benefit from a modernized wiring system.
