Kit Contents:

  2. Standard turn signal flasher, hazard flasher and horn relay mounted on harness.
  3. NEW compact ATO-Style fuse panel that is fully encased in a closed box assembly with coverlid that mounts on the left-hand door hinge pillar under the dash for easy access (mounting hardware included). The fuse coverlid is labeled on the inside identifying all circuits by description and their respective fuse ratings. All high amperage output circuits incorporate the same superior spring steel reinforced terminals that are used in the Highway Series kits.
  4. Harness is laid out and formed to allow for nearly all aftermarket accessories such as; electric gauge packages, heat and air conditioning systems, updated wiper systems, etc.
  5. Many original switch connector bodies - an American Autowire exclusive feature.
  6. Steering column connectors can plug directly into most aftermarket steering columns or stock 1963-67 Corvette columns using the adapter and terminals included in the kit.
  7. Correct original style under dash courtesy lamp assemblies are included.
  8. 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 CLASSIC INSTRUMENTS, DAKOTA DIGITAL, AUTOMETER, VDO, and others (will not service the stock ammeter).
  9. Rear body harness assembly plugs into the main harness at the left kick panel location. Our longer leads allow for stock or custom routing of the wires. Rear body wiring includes stop / tail light lead and back up lead wires along with dis-connectable stop / tail and back up lamp extensions that include the proper “twist in” style tail lamp sockets and accordian style seal boots.

A heavy gauge alternator feed and fusible link are also included for any typical high output 1 wire or internally regulated alternator.
