1. Rhagymadrodd
The REDARC Tow-Pro Elite V3 Electric Brake Controller with Active Calibration is designed to provide smooth and safe braking for trailers. This unit offers proportional braking, ensuring the trailer brakes are applied in proportion to the towing vehicle's brake force. Its compact design and remote head allow for flexible installation in various vehicle types.
This manual provides essential information for the proper installation, operation, and maintenance of your Tow-Pro Elite V3 brake controller. Please read it thoroughly before installation and use to ensure optimal performance and safety.

3. Gosod
Proper installation is crucial for the safe and effective operation of your brake controller. If you are unsure about any step, consult a qualified automotive electrician.
3.1 Gosod Prif Uned
The main unit should be securely mounted in a location that is protected from moisture and physical damage, typically under the dashboard or in a kick panel. Ensure the unit is mounted in the correct orientation as indicated by the product labels for optimal accelerometer performance.

3.2 Gwifro Cysylltiadau
Connect the wiring harness to the main unit. The harness typically includes four color-coded wires:
- Gwifren Ddu: Connect to the positive terminal of the vehicle's battery via a 20A or 30A auto-resetting circuit breaker or fuse.
- Gwifren Gwyn: Connect to a suitable chassis ground location. Ensure a clean, secure connection for reliable operation.
- Gwifren Goch: Connect to the cold side of the vehicle's brake light switch (stoplight signal). This wire detects when the vehicle's brakes are applied.
- Gwifren Las: Connect to the trailer's electric brake output wire. This carries the braking signal to the trailer.

3.3 Remote Head Installation
The remote head should be mounted within easy reach of the driver and in a location that does not obstruct the driver's view or interfere with vehicle controls. Use the provided adhesive pad or mounting bracket to secure the remote head. Route the remote head cable discreetly to the main unit.

4. Gweithrediad
4.1 Gosod a Calibro Cychwynnol
After installation, the unit will perform an initial calibration. Drive the vehicle with the trailer attached on a level surface. The unit will automatically detect the trailer and calibrate its internal sensors. The display will indicate when calibration is complete.
4.2 Manual Brake Control
The remote head features a manual brake button (often labeled 'S' or 'M' for 'Manual' or 'Set'). Pressing this button applies the trailer brakes independently of the vehicle's brakes. This can be used for testing or to reduce trailer sway. The display will show the applied brake force.

4.3 Brake Force Adjustment
Use the 'Up' and 'Down' buttons on the remote head to adjust the overall brake force applied to the trailer. This allows you to fine-tune the braking response to match your trailer's weight and road conditions. The display will show the current brake setting (e.g., B1 to B9).
4.4 Modd Gwrthdroi
When reversing, the brake controller automatically reduces or disables trailer braking to prevent locking up the trailer wheels. The display may show a 'Caution Reverse' message or similar indicator.
5. Gosodiadau a Chyfluniad
The remote head allows access to various settings to customize the controller's behavior.
5.1 Accessing the Setup Menu
Typically, holding down a specific button (refer to the remote head's markings) will enter the setup menu. Navigate through options using the 'Up' and 'Down' buttons.
5.2 Gosodiadau Sydd Ar Gael
- Iaith: Dewiswch eich dewis iaith arddangos.
- Disgleirdeb: Adjust the display brightness for optimal visibility day or night.
- Amser wrth gefn: Configure how long the display remains active before entering a power-saving standby mode.
- Lefelu: Re-calibrate the internal leveling sensor if the unit's mounting orientation has changed or if you experience inconsistent braking.

6. Datrys Problemau
If you encounter issues with your Tow-Pro Elite V3, refer to the following common troubleshooting steps:
6.1 Diagnostic Display
The remote head can display diagnostic information. Access the 'Troubleshoot' or 'Diagnostics' menu (refer to your remote head's specific button functions) to view:
- PŴER: Batri cerbyd cyftage.
- MEWNBWN: Cyftage from the brake light switch.
- ALLBWN: Current being sent to the trailer brakes.
Ensure POWER and INPUT voltages are within expected ranges (e.g., ~12V). If OUTPUT is 0.0A when brakes are applied, check wiring to the trailer.

6.2 Materion Cyffredin
- No Power to Unit: Check the fuse/circuit breaker on the black wire to the battery. Verify battery connections.
- No Trailer Detected: Ensure the trailer is properly connected to the vehicle's trailer connector. Check the blue wire connection.
- Intermittent Braking: Inspect all wiring connections for looseness or corrosion, especially the ground (white wire).
- Incorrect Braking Force: Adjust the brake force setting on the remote head. Re-perform leveling calibration if necessary.
