This harness and ECU kit is for a 2014-2018 5.3L, 6.2L, L83, L86, GM direct injected LT1 58x style V8 engine.
All CBM Motorsports™ harnesses are completely plug and play with switched power, constant power and ground connections required. Harnesses are professionally constructed with brand new OEM GM Delphi connectors and US made TXL (polyethylene cross linked) high temperature wire to GM Specifications.
This is not a modified OEM harness. Every clip, connector and pin is brand new. All blunt cut wires are clearly labeled for easy installation. We use genuine Delphi connectors for every connection (not knock off China plugs).
This is a show quality harness and uses all expandable sleeving, not cheap plastic split loom. All wires are correct AWG and have heat shrink at each end. This is a true USA made harness.
Every harness comes with a four foot lead to mount the computer under a seat, inside the passenger compartment, on a firewall, etc. The package comes with a compact fuse holder and water tight relays for long lasting durability.
All harnesses are 100% quality inspected prior to shipping. Harnesses are available (special order) with longer or shorter trunk based on your application. Please call or email direct for special order parts.
This listing is for a complete standalone harness with ECU, TCM and sensors. The parts included are also available separately.
Please designate the year of your engine and transmission required in the drop down menu above.
