Painless Wiring Chassis Wiring Harness 60617; for 1999 to 2006 GM LS

Our integrated EFI/Chassis harnesses are the perfect solution for anyone doing a complete rewire of a vehicle as well as transplanting a GM Gen III fuel injected engine. This kit is designed for use on 1999-2006 4.8L, 5.3L, & 6.0L Vortec truck engines with a 4L60E transmission. 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. This harness also requires the following mating parts; ECM #12200411 (Painless # 60700) We recommend checking the online manual for the full list of required mating parts prior to ordering.
