Painless Wiring 60522 LS1/LS6 Fuel Injection Wiring Harness Kit

The Painless Wiring 60522 is a complete fuel injection wiring harness specifically engineered for 1997-2004 throttle-by-wire LS1 and LS6 engines paired with 4L60E/4L65E automatic or T56 manual transmissions. This comprehensive harness simplifies engine swaps and rewiring projects with GM color-coded wires, pre-labeled connections, and a modular design for straightforward installation.

Key Features:

• Standard length design with 4 feet of clearance from intake manifold to fuse block/ECM mounting location
• Integrated 8-circuit modular fuse block for centralized circuit protection
• GM factory color-coded wiring with identification labels for easy installation
• Ideal for mounting ECM and fuse block under dash or in glove box
• Non-emissions configuration (emissions-related connections not included)

Required Mating Components (Not Included):

• ECM #12200411
• TAC Module #12578953
• Accelerator Pedal #12565643

Protected Circuits:

• Dual 40-amp ignition relays for driver and passenger side injectors and coils
• Fuel pump circuit with dedicated relay
• ECM power and malfunction indicator lamp
• Heated oxygen sensors and mass airflow sensor
• Transmission and throttle actuator control module
• Diagnostic link connector power and brake switch

Included Connections:

• Engine Management: ECM, crank position sensor, cam position sensor, MAP sensor, mass airflow/intake air temperature sensor, throttle position sensor, engine coolant temperature sensor
• Fuel System: Fuel injectors, fuel pump, fuel pump relay, fuel pump test connector
• Ignition System: Ignition coils, ignition switch signal, starter, alternator
• Transmission: 4L60E/4L65E or T56 connections, vehicle speed sensor, VSS speedometer output, gear indicator switch, reverse lockout solenoid, skip shift solenoid and light
• Throttle Control: Throttle actuator control module, TAC motor, accelerator pedal position sensor with pigtail
• Sensors: Driver and passenger front O2 sensors, driver and passenger knock sensors, oil pressure sensor, brake switch, clutch pedal position sensor
• Accessories: Tachometer output, cruise control, fan relay grounds (ECM-activated for fans #1 and #2), data link connector, malfunction indicator lamp
• Grounds: Multiple ground connections for proper system operation

This harness is the ideal solution for LS swap projects requiring a clean, professional wiring installation with all necessary circuits for complete engine and transmission control.
