Proflow's LS standalone wiring harness kits offer the best in aesthetics and reliability, designed specifically for GM LS engines produced from 1997 to 2004. They are available for both cable-driven and fly-by-wire vehicles with 4L60E or T56 transmissions, and will completely replace your old harness.

Note: These are based off original LS harnesses. Some plugs may be different depending on engine build date. No oil pressure sensor wire is provided/catered for, as this is a aftermarket loom and relies on aftermarket engine management to cater for oil pressure monitoring
