Harnesses

New-construction LS swap harnesses, built from scratch to your combination. TEFZEL or TXL wire, DR-25 or fiberglass loom, Deutsch and Delphi terminals, custom-made Bussmann fuse boxes and relays, mil-spec concentric twisting, every cable labeled.

Coverage is one size fits all across LS engines and ECUs. What changes the build is your transmission, your throttle type, and anything on the engine that is not stock.
