Engine Harness

All American Autowire Engine “Factory Fit” engine harnesses are designed to be a plug-and-play replacement for your original factory engine harness. If you’ve got an original factory wiring harness, this is one of the best replacement options on the market. American Autowire uses the same connectors as your original wiring harness, so you don’t have to replace every connection. The harness is also configured just like the factory original, so it’s easy to follow the factory routing and place this harness the same way. This American Autowire Engine Harness – part number 31667 – is an accurate reproduction of an original GM wiring harness. Like all American Autowire products, this product is designed to be an exact fit replacement of an original harness. Simply unplug the factory harness, plug this harness in (it uses all the same original plugs as the factory harness), and you’re good to go. Assembled in the USA, American Autowire harnesses are one of our most popular types of parts. This product fits a 1973 Nova or Chevy II 6-Cylinder with Warning Lights. If you have a question about this product – or if you can’t find the fitment you need – please don’t hesitate to contact us. We offer free parts look-up by phone during normal business hours. Installation is fairly straightforward, but it’s a good idea to use a pen and masking tape to “tag” every connection before you remove the factory harness. Then, you can layout the old harness next to the new one, match up the connections, tag the new harness the same way, and then match up your connections as you go. It takes a little more work to prepare, but it can save you a lot of time and trouble later.
