EFI Wiring Harness - Extra Length - GM LS-Series 2003-06 - Kit
Fuel Injection Wiring Harness; Mechanical Throttle Only; Extra Length;
Designed for 1999-2006 4.8L, 5.3L, 6.0L mechanical throttle body engines using LS1/LS6 PCM and 4L60E, 4L65E, 4L70E, 4L80E, 4L85E or manual trans. 2003-2006 Engines require mechanical throttle body. 2003-2006 engines which were originally flex fuel will also require Delphi Multec 2 (factory truck style) injectors. Includes 10 circuit weatherproof fuse block and GM color coded wires with labels. Extended length harness allows eight feet from the back of the intake manifold to where the fuse block and ECM mount. Perfect when mounting these components under the seat or in the center console. Does not support Flex Fuel USCAR Injectors. Fuse block protects following circuits: Air Pump & Air Pump Solenoid, Canister Purge, Canister Vent, Transmission, & Park Neutral Position Switch, Driver Side Injectors and Coils, Dual 40 amp Ignition Relays, Fuel Pump, Heated O2 Sensors, Mass Airflow Sensor, & Brake Switch, Pass Side Injectors and Coils, ECM B+ & DLC B+, ECM IGN and Malfunction Indicator Lamp. Includes connections for: A/C Request, Air Pump, Air Pump Relay, Air Pump Solenoid, Alternator, Brake Switch, Cam Position Sensor, Canister Purge, Canister Vent, Crank Position Sensor, Data Link Connector, Driver/Pass Front O2 Sensors, EGR Valve, Engine Coolant Temperature, Fan #1 Relay Ground ECM Activation, Fan #2 Relay Ground ECM Activation, Fuel Pump, Fuel Pump Relay, Fuel Pump Test, Grounds, Idle Air Control, Ignition Coils, Ignition Switch Signal, Injectors, Input Speed Sensor, Knock Sensors, Malfunction Indicator Lamp, MAP Sensor, Mass Airflow Sensor & Intake Air Temperature Sensor, Output Speed Sensor, Park/Neutral Switch, ECM, Reverse Lights, Starter, Starter Relay, Tachometer, Throttle Position Sensor, 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.
