Doing it yourself sometimes doesn’t pan out. The typical LS, Gen 5 LT1 or Duramax harness has hundreds of individual wires and each has a specific place in the harness.  While setting it up for standalone yourself is possible with the right tools and information, you will also need to bring plenty of patience. Rely on our knowledge and experience instead to provide you with a harness that requires just 4 connections to make your LS, Gen V LT1 or Duramax Swap Engine run. Take a look at the LS Engine, Gen 5 LT and Duramax tabs for more details and examples of our work.
