Installation Instructions for T-Connector Adapter

Part Numbers:

• 118404

Tools Required:

• Drill with a 3/32” drill bit
• Phillips head screwdriver

Step-by-Step Instructions:

1. Locate the Vehicle Wiring:

   • Open the trunk and remove the plastic wing nuts located behind each taillight.
   • Pull back the carpet to expose the vehicle's taillight wiring.

2. Driver’s Side Connection:

   • Disconnect the vehicle's wire harness from the driver’s side taillight socket by sliding the red locking tab to the unlocked position.
   • Plug the T-Connector with the yellow wire between the vehicle's wiring harness and taillight socket.
   • Ensure all connectors are fully inserted and the locking tabs are secure.

3. Passenger’s Side Connection:

   • Route the T-Connector with the green wire along the threshold to the passenger’s side of the vehicle.
   • Push the wiring between the vehicle body and the carpet.
   • Repeat the connection process for the passenger’s side using the T-Connector with the green wire.

4. Ground the White Wire:

   • Locate a suitable grounding point near the adapter, such as the vehicle frame or crossmember.
   • Clean the grounding area to remove dirt and rustproofing.
   • Drill a 3/32” hole and secure the white wire using the provided eyelet and screw.
   • Caution: Verify what is behind any surface before drilling to avoid damage or injury. Do not drill into exposed surfaces.

5. Reassembly:

   • Reinstall the carpet, plastic wing nuts, and any other clips or panels removed during installation.
   • Be careful not to cut or pinch the wires during reassembly.

6. Test the Installation:

   • Verify the T-Connector functionality using a test light or trailer.

   Specifications:

   • Max. stop/turn light: 1 per side (7.5 amps)
   • Max. tail lights: (7.5 amps)

Safety Notes:

• Do not exceed the towing manufacturer’s rating or the unit specifications.
• Overloading circuits can cause fires.
• Ensure all connections are secure and properly tested.

Manufacturer Notes:

• Read and follow all warnings and instructions provided.
• Refer to the vehicle owner’s manual for additional guidance.

Installation Instructions for 4-Way to 7-Way Adapter and Brake Control Wiring

Tools Required:

• Phillips Head Screwdriver
• Drill with 3/32" Drill Bit
• 10mm Socket & Ratchet or Wrench
• Wire Crimpers
• Wire Cutters
• Test Light or Multimeter
• Cable Ties

Part 1: Install the 4-Way to 7-Way Adapter

Step-by-Step Instructions:

1. Mount the Adapter:

   • Choose a suitable mounting point on the vehicle, typically near the hitch.
   • Use the provided bracket and screws to secure the adapter.

2. Connect the 4-Flat Plug:

   • Plug the 4-flat connector on the adapter into the existing 4-flat plug on the vehicle.
   • This connection enables tail lights, left turn, and right turn signals.

3. Ground the Adapter:

   • Locate a clean, solid grounding point near the adapter.
   • Drill a 3/32" hole if necessary and secure the white ground wire from the adapter using the provided screw and eyelet.

4. Leave Additional Wires Disconnected:

   • The following wires will remain disconnected until Part 2:
     • Black Wire: Power from the battery.
     • Blue Wire: Brake control output.
     • Yellow Wire: Reverse light (optional; leave disconnected unless needed).

5. Test Initial Connection:

   • Use a test light or trailer to verify functionality of the 4-way connections (tail lights, turn signals).

Part 2: Install Brake Control Wiring

Step-by-Step Instructions:

1. Mount Circuit Breakers:

   • Install two 30A circuit breakers on the firewall or another suitable location near the battery.
   • Use self-tapping screws to mount them securely.

2. Route Power Wires:

   • Connect the black 12-gauge wire from the 7-way adapter to the auxiliary side of one circuit breaker (this powers the 7-way socket).
   • Run a heavy-gauge wire from the battery's positive terminal to the battery side of this circuit breaker, using a ring terminal.
   • Run another heavy-gauge wire from the battery's positive terminal to the auxiliary side of the second circuit breaker (for the brake controller).

3. Install the Brake Controller:

   • Mount the brake controller under the dash on a firm surface.
   • Use the following connections:
     • Red Wire: Connect to the cold side of the brake switch (active only when the brake pedal is pressed).
     • Blue Wire: Connect to the blue wire on the 7-way adapter for trailer brakes.
     • White Wire: Connect to a solid ground point on the vehicle body.
     • Black Wire: Connect to the auxiliary side of the second 30A circuit breaker (provides power to the brake controller).

4. Optional: Connect Reverse Light Circuit:

   • If the trailer has a reverse light circuit, connect the yellow wire from the 7-way adapter to the vehicle’s reverse light circuit.

5. Reconnect the Battery:

   • Reattach the negative battery cable and ensure all connections are secure.
   • Insert the fuses into both circuit breakers.

6. Secure All Wires:

   • Use cable ties to secure all loose wires and prevent damage or rattling.

7. Test the System:

   • Verify functionality of all circuits (running lights, turn signals, brake lights, and brake controller output).
   • If applicable, test the reverse light circuit.

Notes:

• Most installations will only require connecting the black and blue wires from the 7-way adapter.
• Leave the yellow wire disconnected unless the trailer has a reverse light or surge brake lockout circuit.
• Always adhere to safety guidelines and verify all connections before use.

Warning: Incorrect wiring can cause damage to the vehicle or trailer. Test all connections carefully before use.
