Painless Wiring 60217 LS Engine Fuel Injection Wiring Harness Kit

The Painless Wiring 60217 is a complete fuel injection wiring harness designed specifically for 1999-2006 GM 4.8L, 5.3L, and 6.0L LS engines with mechanical throttle bodies. This harness is compatible with LS1/LS6 PCM configurations and supports 4L60E, 4L65E, 4L70E, 4L80E, 4L85E automatic transmissions, as well as manual transmissions.

Key Features:

• Integrated 10-circuit weatherproof fuse block for critical circuit protection
• GM color-coded wires with clear labels for simplified installation
• Standard length design with 4-foot reach from intake manifold to fuse block and ECM mounting location
• Ideal for under-dash or glove box component mounting
• Dual 40-amp ignition relays for reliable power distribution
• Comprehensive connector coverage for all essential engine management components

Important Compatibility Notes:

• 2003-2006 engines require mechanical throttle body installation (originally equipped with drive-by-wire)
• 2003-2006 flex fuel engines must use Delphi Multec 2 (factory truck style) injectors
• Does not support USCAR-style flex fuel injectors

Protected Circuits: The integrated fuse block protects air pump and solenoid, canister purge and vent, transmission and park/neutral position switch, driver and passenger side injectors and coils, fuel pump, heated O2 sensors, mass airflow sensor, brake switch, ECM power, and malfunction indicator lamp circuits.

Included Connections: This harness provides plug-and-play connections for A/C request, air pump system components, alternator, brake switch, cam and crank position sensors, EVAP system, data link connector, oxygen sensors, EGR valve, engine coolant temperature sensor, cooling fan relays, fuel pump and relay, all ignition components, injectors, transmission speed sensors, knock sensors, check engine light, MAP sensor, MAF/IAT sensor, park/neutral switch, PCM, reverse lights, starter system, tachometer output, and throttle position sensor.

This comprehensive wiring solution simplifies LS engine swap installations by providing a complete, organized harness with professional-grade weatherproof protection and clear labeling for confident DIY installation.
