What Happens If You Turbo a 5.3L Yukon With No Other Mods? PART 2: Fuel Injector Upgrade! (RIP 4L60)
What happens here
Due to different connector types on the new injectors, the existing wiring harnesses need to be modified. The team decides to use butt connectors with heat shrink. Each wire on the old connector is cut, the ends are stripped, and then crimped into the appropriate butt connector along with the corresponding wire from the new injector pigtail. A heat gun is used to shrink the heat shrink tubing over the butt connectors for insulation and weather sealing. This process is repeated for all eight injectors.
Goal: Connect new injector pigtails to the vehicle's wiring harness.
