The best harness available for a tri fiv

August 11, 2014
I have installed several wiring harnesses in hot rods and muscle cars, and American Autowire is by far the best on the market. These have all of the factory type connectors that many aftermarket wiring kits do not have. You end up spending the same amount of money tracking down all the rest of the pigtails, connectors, and other pieces to complete the install. I won't buy anything besides AAW in the future.
Pros:
  • factory fit connectors
  • you get a detailed diagram
Yes, I recommend this product.

This is a complete wiring harness for the 55-56 Chevy cars, it makes use of modern day fuse block and comes with all the connectors to plug right into the factory gauges and accessories. It also comes with new headlight, dimmer, ignition switches and connectors to match up to many aftermarket gauges. Installation is simple and splicing would be limited to changing the ends if going to aftermarket gauges or accessories.
