The Wiring Specialties Pro-Series LS1 wiring harness is a Brand New, Tucked, Plug and Play harness that was designed and tested by our in-house experts specifically for any classic Chevy NON-EFI chassis or race car with an LS1 engine swap. It was modeled on the actual LS1 engine and is race-proven to perform in challenging conditions.
Note: LS2 and up engines, additional accessories and other injector types are subject to additional fees. Please call us if you have a drive-by-wire engine.
