4. Installation Instructions

This kit is commonly used for the fuel pump fuse relocation on certain Ford F-150 models to address issues with the original fuse location. The following steps outline a general installation procedure. Specific vehicle configurations may vary.

Required Tools:

• Wire cutters/strippers
• Soldering iron and solder (recommended for a secure connection)
• Heat gun (for heat shrink tubing)
• Multimeter (for verifying circuits, optional but recommended)
• Basic hand tools (e.g., screwdriver, trim removal tools)

Procedure:

1. Prepare Vehicle: Ensure the vehicle is turned off and the ignition key is removed. Disconnect the negative terminal of the vehicle's battery to prevent accidental electrical discharge.
2. Locate Fuse Box: Identify the main power distribution box, typically located under the hood. Carefully unclip and lift the fuse box assembly to access the wiring harness underneath. Exercise caution as plastic tabs can be brittle.
3. Identify Fuel Pump Wire: Locate the wire associated with the fuel pump circuit. This is often a red and blue wire. It is crucial to identify the correct wire; it is typically the thicker of any red/blue wires present. Refer to your vehicle's specific wiring diagram if unsure.
4. Cut and Strip Wire: Once the correct fuel pump wire is identified, carefully cut it. Strip approximately 1/2 inch (1.25 cm) of insulation from both ends of the cut wire.
5. Prepare New Terminal Wire: Take the pre-wired terminal from the kit. Strip approximately 1/2 inch (1.25 cm) of insulation from the free end of this wire.
6. Solder Connections:
   • Slide one of the heat shrink tubes over one of the stripped ends of the vehicle's fuel pump wire.
   • Connect the free end of the new terminal wire to one of the cut ends of the vehicle's fuel pump wire. Twist the exposed copper strands together securely.
   • Solder the connection to ensure a strong, permanent electrical bond. Allow the solder to cool.
   • Slide the heat shrink tube over the soldered connection and apply heat with a heat gun until it shrinks tightly, sealing the connection.
   • Repeat this process for the other cut end of the vehicle's fuel pump wire, connecting it to the remaining wire from the new terminal (if applicable, depending on the specific kit design for inline fuse relocation).
7. Install New Fuse: Insert the provided 20 Amp mini fuse into the new terminal's fuse holder.
8. Secure Wiring: Route the new wiring neatly and securely within the fuse box area, ensuring it does not interfere with any moving parts or get pinched.
9. Reassemble Fuse Box: Carefully lower and clip the fuse box assembly back into its original position.
10. Apply Label: Affix the new fuse block label to the fuse box cover, indicating the new location or modification of the fuel pump fuse.
11. Reconnect Battery: Reconnect the negative terminal of the vehicle's battery.
12. Test System: Start the vehicle and verify that the fuel pump operates correctly and there are no warning lights.

5. Operation

The Ford Genuine EL3Z-14293-A Terminal Kit is a passive component designed to integrate into your vehicle's electrical system. Once correctly installed, it functions automatically as part of the fuel pump circuit, providing reliable power and protection via the relocated fuse.

6. Maintenance

This terminal kit requires minimal maintenance. Periodically inspect the connections for any signs of corrosion, looseness, or damage. Ensure the heat shrink tubing remains intact and provides a secure seal. If the fuse blows, replace it only with a fuse of the identical amperage (20 Amp) and type. Using a fuse with a different rating can lead to electrical system damage or fire.

7. Troubleshooting

Vehicle Does Not Start / Fuel Pump Not Operating:

• Check Fuse: Inspect the 20 Amp fuse installed with the kit. If it is blown (broken filament), replace it with a new 20 Amp mini fuse.
• Inspect Connections: Verify that all soldered and heat-shrunk connections are secure and free from corrosion or damage.
• Verify Wire Identification: Double-check that the correct fuel pump wire was cut and connected during installation. Incorrect wire identification can lead to system malfunction.
• Battery Connection: Ensure the vehicle's battery terminals are clean and securely connected.

If the issue persists after performing these checks, it is recommended to consult a qualified automotive technician for further diagnosis.
