Fuel Injection Wiring Harness: Complete Installation Instructions

The wiring harness holds the wires of the fuel injector. Though wiring harnesses are high-quality components that take a long time to wear out, they'll get damaged eventually. When that happens, you have to be ready to replace the wiring harness of your vehicle right away. If you're driving a vehicle that's equipped with a Duramax LLY injector, here are the things that you can do to replace the damaged wiring harness.

Difficulty level: Difficult

Tools needed:

  • Ratchet
  • Socket
  • Screwdriver
  • Replacement wiring harness

Step 1: Park your vehicle, and turn off its engine.

Step 2: Open the hood, and locate the fuse box in the passenger's area.

Step 3: In order to relieve the pressure in the fuel system, carefully remove the fuel pump fuse.

Step 4: Carefully disconnect the negative cable from the battery.

Step 5: Find your vehicle's fuel injectors. Usually, these components can be found in a spot where the engine block is connected to the fuel line. Depending on the engine size, your vehicle might have several fuel injectors.

Step 6: Find the old wiring harness. Check for rust, cracks and dirt. If the wiring harness isn't able to hold all the wires properly, then replace it with a new one.

Step 7: Push the center of wiring harness to release it from the fuel injector. Make sure that you slide the old wiring harness down the fuel line.

Step 8: Depress the clip that slides over the old wiring harness so you can release it from the fuel line.

Step 9: Put the new wiring harness in place by sliding it onto the fuel line just beneath the clip. You should be able to hear a clicking sound once the new wiring harness is secured.

Step 10: Make sure that the fuel line and the wiring harness is aligned with the corresponding fuel injector.

Step 11: Secure the new wiring harness by pressing the clip that will hold it on the fuel injector.

Step 12: Reinstall the fuel pump fuse box and reconnect the negative cable to the battery.
