Chassis Wiring Harness; For Use w/Mechanical Throttle Body;
Designed for use on any 2007-2012 4.8L, 5.3L, 6.0L, & 6.2L Vortec truck engines with throttle by wire. It uses the factory ECM & TCM and will operate engines with or without variable valve timing (VVT) and active fuel management (displacement on demand or DOD). Does not support flex fuel. Includes a 10 circuit weatherproof fuse block & bracket, GM color coded wires with labels, and all the required terminals and connectors. This standard length harness allows four 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 dash or in the glove box. This harness also requires the following mating parts; ECM #12597121 or #12612384; TCM #24234503; Accelerator Pedal #25832864 or #25835421. The fuse block protects: ECM and Data Link Connector B+, ECM and Malfunction Indicator Lamp, Fuel Pump, Heated O2 Sensors, Ignition Coils, Injectors, Mass Airflow and Valve Lifter Oil Manifold (DOD), TCM, TCM B+, Transmission, 40A Cooling fan Relay and Circuit Breaker (ECM Activated), 20A Fuel Pump Relay, 40A & 20A Ignition Relays. Includes connections for: Accelerator Pedal Position Sensor, Alternator (incl. 4 gauge power wire), Brake Switch, Cam Position/Cam Phazer Sensor, Cooling Fan, Crank Position Sensor, Data Link Connector Driver/Pass Front O2 Sensors, Driver/Pass Knock Sensors, ECM, Engine Coolant Temperature, Fuel Pump, Grounds , Ignition Coils, Ignition Switch Signal, Injectors, Input Speed Sensor 4L80E/4L85E, Malfunction Indicator Lamp, MAP Sensor, Mass Airflow/Intake Air Temperature Sensor, Oil Pressure Sensor, PRNDL Switch, Reverse Lights, Starter, TCM, Throttle Body, Transmission, Valve Lifter Oil Manifold (DOD), 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.
