So there’s an older muscle car sitting in the garage, sans engine, and you’ve decided it’s time to update the engine bay with an LS swap. Chasing down all of the harnesses and connectors, and then spending the time to pick out only what’s required to run the engine is a huge challenge. Thankfully the team at Wiring Specialties has the solution in the form of their plug-and-play LS harness that greatly simplifies and streamlines the process. There are options for transmission harnesses and even an HP Tuners PCM flash–check it out!
