Painless Wiring - 60221
EFI Wiring Harness - Extra Length - GM LS-Series 2003-06 - Kit
Fuel Injection Wiring Harness; Throttle By Wire; Standard Length; Incl. Mounting Hardware;
Designed for use on 1999-2006 4.8L, 5.3L, 6.0L throttle by wire engines with 4L60E-4L85E or manual trans. 1999-2002 engines require a 2003-2006 TBW throttle body. Engine codes supported are LR4, LM7, LM4, LQ4 and LQ9. Will support flex fuel and non flex fuel engines. Flex fuel engines will require inline fuel composition sensor in order to run E85 fuel. Includes 10 circuit weatherproof fuse block & bracket and GM color coded wires with labels. Standard length harness allows four feet from the back of the intake manifold to where the fuse block and ECM mount. Perfect for mounting these components under the dash or in the glove box. Fuse block protects the following circuits: Brake and Cruise Switch, Dual 40 amp Ignition Relays, ECM (IGN), ECM B+, Fuel Injectors, Fuel Pump, Heated O2 Sensors, Ignition Coils, Mass Airflow and Fuel, Compensation Sensor, Throttle Actuator Control Module, Transmission and Park Neutral Position Switch, 20 Amp Cooling Fan Relay, 20 Amp Fuel Pump Relay. Includes connections for: A/C Request, Accelerator Pedal Position Sensor, Alternator, Brake Switch, Cam Position Sensor, Cooling Fans, Crank Position Sensor, Cruise Control ,Data Link Connector, Driver/Pass Front O2 Sensors, ECM, Engine Coolant Temperature, Fuel Compensation Sensor, Fuel Pump, Fuel Pump Test , Grounds, Ignition Coils, Ignition Switch Signal, Injectors - Gas & Flex Fuel Sub-Harness, Input Speed Sensor, Knock Sensors, Malfunction Indicator Lamp, MAP Sensor, Mass Airflow / Intake Air Temperature Sensor, Output Speed Sensor, Park/Neutral Switch, Reverse Lights, Starter, Starter Relay Activation, Tachometer, Throttle Actuator Control Module, Throttle Actuator Control Module to Accelerator Pedal Pigtail, Throttle Body, Transmission, VSS Output for Speedometer. PLEASE NOTE: This harness is standalone and is not intended to replace the OEM engine wiring. Standalone harnesses are intended to run the designated engine & transmission only, generally when swapped into another vehicle.
