HOW TO USE:

• Preparation: Ensure the vehicle’s ignition is turned off and the engine is cool. Disconnect the negative battery terminal for safety.
• Locate Injectors: Identify the fuel injectors on the engine. Each injector will have a wiring connector attached to it.
• Disconnect Old Harness: Carefully disconnect the existing wiring harness connectors from each fuel injector. Take note of the orientation of the connectors if necessary.
• Connect New Sub-Harnesses: Take one of the new FiTech 38350-4-2 sub-harnesses. Connect one end of the sub-harness to the corresponding connector on the FiTech main wiring harness.
• Attach to Injectors: Connect the other end of the sub-harness to the fuel injectors. Ensure the connectors are fully seated and secure.
• Repeat for Other Side: Repeat steps 4 and 5 for the second sub-harness, connecting it to the appropriate connectors on the main harness and the remaining injectors.
• Secure Wiring: Ensure the wiring is routed safely away from moving engine parts and heat sources. Use any existing clips or ties to secure the harnesses.
• Reconnect Battery: Reconnect the negative battery terminal.
• Testing: Turn the ignition key to the “on” position (without starting the engine) and check for any error codes or unusual behavior. Start the engine and monitor its performance to ensure the new sub-harnesses are functioning correctly.
