Fuel Injection Wiring Harness; Mechanical Throttle Only; Standard Length;
This harness is designed for the 1999-2006 4.8L, 5.3L, 6.0L mechanical throttle body engines using an LS1 / LS6 PCM with a 4L60E, 4L65E, 4L70E, 4L80E, 4L85E,or manual transmission. 2003-2006 Engines will require a mechanical throttle body to be installed. 2003-2006 engines which were originally flex fuel will also require Delphi Multec 2 (factory truck style) injectors to be installed. Included with this harness is a 10 circuit weatherproof fuse block and GM color coded wires with labels for easy installation. This extended length harness allows eight feet from the back of the intake manifold to where the fuse block and ECM mount. Perfect for those that plan to mount these components under the seat or in the center console. **Please note that this harness does not support Flex Fuel USCAR Injectors.** The Fuse Block Protects The 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. This harness includes connections for the following components: 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.
