60617 1999-2006 GM Gen III 4.8/5.3/6.0L Integrated EFI & Chassis Harness – Mech.


Are you rewiring your GM truck? This wiring harness from Painless Performance®™ is the answer to all your wiring needs. The chassis wiring and fuel injection wiring are fully integrated into a single 26 circuit/7 relay fuse block, eliminating the need to have separate fuses and relays for the fuel injection. The chassis harness connections are the same GM color coded connections as our 10201 kit. The fuel injection connections include the same labels connections as our 60217 harnesses. These harnesses do not support flex fuel engines and require the use of a mechanical throttle body. Included in this kit you will also find all the required terminals & connectors for easy installation.
