Link ECU LS Engine Harness

Link ECU LS Engine Harness Kits

Pre-built engine harness kits for GM LS swap projects, bundled with Link G4X standalone ECUs. YPG Motorsport stocks the complete Link LS harness range covering Gen 3 (LS1, LS6) and Gen 4 (LS2, LS3, LS7, L76, L77, L98, L99) engines, available in cable throttle and drive-by-wire configurations.

Each kit bundles a G4X StormX or G4X XtremeX ECU with a purpose-built engine harness, fuse box, and relay panel — everything needed to wire an LS engine into a non-GM chassis without building a custom harness from scratch. The harness connects directly to the LS engine sensors, injectors, coils, and ancillaries. Drive-by-wire kits include the electronic throttle body connector and pedal input wiring; cable throttle kits are designed for manual throttle body setups common in older chassis swaps.

Individual harness components are also available for builders who already own a Link ECU: adapter looms, extension harnesses, fuse box assemblies, and connector kits. All LS harness products are designed and manufactured by Link ECU in New Zealand.

Ships worldwide via FedEx International Priority. See the full Link ECU catalogue for WireIn ECUs, Plug-In ECUs, displays, and PDMs.
