Our Gen IV LS2 standalone harness is designed for installing these new GM EFI engines into your ride, whatever it may be. This swap harness is specific for 2005-2006 24x engines with a Drive by Wire (Electronic) Throttle Body, EV6 Injectors, and a 4L60e Transmission. This standalone harness is made for the E40 ECM, and has to be used with a 24x engine.

Why BP Automotive?

All of our LS2 Gen IV standalone harnesses are made with GM color coded TXL wire to meet or exceed OEM standards!  All circuits that are routed in high heat areas like the O2 sensors, knock sensors, and the crank position are covered with 1200* Fiberglass Braid. We only use OEM Delphi, Kostal, Bosch, Molex, and Yazaki connectors, terminals, and seals on our standalone harnesses. All connectors that have a Connector Position Assurance Lock on a factory harness will have them on our LS2 standalone harnesses, just like factory. Our Gen IV LS2 standalone harness also includes a sliding, snug fitting Delphi Grommet that can be positioned on the main harness line to seal your firewall.

Our LS2 standalone swap harnesses are 5 foot long from the rear of the intake, this enables you to mount the ECM and Fuse Block in the passenger compartment for a hidden, clean look! This harness is for pre-emissions vehicles or for off road use only. This standalone harness does not have provisions for EGR, AIR, EVAP, or Rear O2 Sensors. Our LS3 Standalone harnesses are also routed for a nice, clean, simple installation that takes just minutes!

Additional Info

Our LS swap harnesses also require the removal of the VATS and emissions systems from the ECM. BP Automotive offers this service with a discount when purchasing a new harness. This harness also requires the use of an E40 ECM, which can also be purchased from BP Automotive.
