1999-2006 GM Gen III 4.8/5.3/6.0L Integrated EFI and Chassis Harness - Mech. TB
Painless Performance 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, and 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 the PPP10201 kit. The fuel injection connections include the same labels connections as our PPP60217 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 and connectors for easy installation.
This harness also requires the following mating parts; ECM #12200411 (Painless # PPP60700)
We recommend checking the online manual for the full list of required mating parts prior to ordering.
Fitment:
- Engine: 4.8L, 5.3L, 6.0L w/ Mechanical Throttle Body
- Trans.: 4L60E
