Part Number: PFEWH1201

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
