Tools Required:
- Hot Air Gun or Appropriate Heat Source
- Wire Crimpers
- Drill (3/32” Drill Bit)
- Phillips Head Screwdriver
- Circuit Tester
Step-by-Step Instructions:
Step 1: Locate the Taillight Wiring Harness
- Access the vehicle's taillight wiring harness.
- Using the provided instructions, identify the appropriate wires for connection:
- Green Wire: Right Turn & Stop
- Yellow Wire: Left Turn & Stop
- Brown Wire: Taillights
- White Wire: Ground
Step 2: Make the Electrical Connections
-
Match the color-coded wires from the wiring kit to the corresponding vehicle wires.
- Use a circuit tester to verify each wire's function before connecting.
- CAUTION: Test one wire at a time to prevent damage to electronic components.
-
Connect the wires using the provided insulated butt connectors:
- Strip the ends of each wire and seat them properly in the connector.
- Use a crimping tool designed for insulated splices to secure the connections.
-
Heat the connectors:
- Apply heat directly to the center of each splice using a hot air gun.
- Work from the center outward until the tubing recovers and adhesive flows.
- Allow the connections to cool before inspecting for integrity.
Step 3: Ground the System
- Locate a grounding point near the wiring harness, such as the vehicle frame or cross member.
- Do not drill into the vehicle floor or bed.
- Clean the area to remove dirt, rust, or undercoating.
- Drill a 3/32" hole at the grounding point and secure the white wire using the provided eyelet and screw.
Step 4: Verify the Installation
- Test all connections using a circuit tester or trailer:
- Verify the functionality of taillights, turn signals, and brake lights.
- Ensure all connections are complete and secure.
- If issues are identified, double-check the wiring and connections for errors.
Step 5: Store the 4-Flat Connector
- Store the 4-flat connector in the rear cargo area when not in use to protect it from damage and environmental exposure.
Warnings and Notes:
- WARNING: Overloading a circuit can cause fires. Do not exceed the following limits:

- Tail Lights: 7.5 amps
- WARNING: Always verify what is behind any surface before drilling to avoid vehicle damage or injury.
- NOTE: Trailer lighting that requires more than 7.5 amps per circuit must use a Trailer Light Power Converter.
- NOTE: If your trailer requires a plug other than the 4-flat, consult your dealer for optional 6-way or 7-way adapters.
Maintenance:
- Inspect the wiring harness periodically for damage, corrosion, or loose connections.
- Reapply heat to connectors if the adhesive seal weakens.
Specifications:
- Maximum Load:
- Stop/Turn Lights: 7.5 amps (1 per side)
- Tail Lights: 7.5 amps
