Our Engine Controller Kits are designed for installing these new GM EFI engines into your ride, whatever it may be. The harness included with this kit is specific for 2009-2014 LSA Engines and a T56/TR6060/Manual/Non-Electric Automatic Transmission. This kit includes a Brand New LSA Swap Harness, a BRAND NEW ECM, Brand New AC Delco O2 Sensors, Brand New AC Delco Mass Air Flow with Mounting Flange, and a Brand New Accelerator Pedal. Most competitors are selling used ECM/TCM with their kits. Not Here at BP Automotive! All harnesses are made with GM color coded TXL wire to meet or exceed OEM standards! All circuits that are ran by heat like the O2 sensor circuits are covered with 1200* Fiberglass Braid. We only use Delphi, Kostal, Bosch, Molex, and Yazaki connectors, terminals, and seals on our harnesses, just like an OEM harness. All connectors that have Connector Position Assurance Lock on a factory harness have them on our harnesses also. The harnesses also include a Delphi Grommet that can be positioned on the main harness line to seal your firewall. 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. Harnesses are for pre-emissions vehicles or for off road use only. Harnesses do not have provisions for EGR, AIR, EVAP, or Rear O2 Sensors. We can add these for an additional cost, however in most cases they are not needed.
