Painless Wiring 60509 Fuel Injection Wiring Harness

Designed for the 1998-2002 LS1 mechanical throttle body engines using a 1999+ LS1 / LS6 ECM and 4L60E/4L65E automatic or T56 manual trans. Will also work on 1997-2004 Throttle By Wire (TBW) LS1/LS6 engines changed to mechanical throttle body or any 1999-2006 (4.8, 5.3, & 6.2) Vortec truck engine which has been changed to a factory of aftermarket LS1 intake manifold, mechanical throttle body, and injectors. Harnesses do not include any emissions related connections but are available separate. Includes an 8 circuit modular 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. Fuse block protects the following circuits: DLC B+, 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 and Malfunction Indicator Lamp, ECM B+, Transmission. Includes connections for: Alternator, Brake Switch, Cam Position Sensor, Crank Position Sensor, Data Link Connector, Driver/Pass Front O2 Sensors, Engine Coolant Temperature, Fan #1 Relay Ground ECM Activation, Fan #2 Relay Ground ECM Activation, Fuel Pump, Fuel Pump Relay, Fuel Pump Test , Gear Indicator Switch, Grounds, Idle Air Control, Ignition Coils, Ignition Switch Signal, Injectors, Intake Air Temperature Sensor, Knock Sensors, Malfunction Indicator Lamp, MAP Sensor, Mass Airflow Sensor, ECM, Reverse Lockout Solenoid, Skip Shift Light, Skip Shift Solenoid, Starter, Tachometer, Throttle Position Sensor, Transmission, VATS, Vehicle Speed Sensor, 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.
