Step-by-Step Instructions:
-
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.
-
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.
-
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.
-
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).
- The following wires will remain disconnected until Part 2:
-
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:
-
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.
-
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).
-
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).
-
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.
-
Reconnect the Battery:
- Reattach the negative battery cable and ensure all connections are secure.
- Insert the fuses into both circuit breakers.
-
Secure All Wires:
- Use cable ties to secure all loose wires and prevent damage or rattling.
-
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.
