Parts & Tools You’ll Need

Step 1: Diagnose Brake Controller Failure

Begin by disconnecting the negative battery terminal to ensure safety while working on electrical systems. Locate the existing brake controller, typically mounted beneath the dashboard on the driver’s side of the tow vehicle. Use the Trailer Wiring Test Tool to check for power and ground signals at the controller’s connector—you should read 12V on the power wire and solid ground on the negative line. If the test tool shows no voltage output to the trailer brakes or erratic readings, the controller has failed and requires replacement. Document which wires connect to your current controller before removal, using the Electrical Tape + Wire Labels to mark each connection clearly.

Step 2: Remove Old Brake Controller Assembly

Disconnect the OEM Plug-In Brake Wiring Adapter from the existing controller by gently releasing the locking tabs on both sides of the connector. Unbolt the controller from its mounting location using a socket wrench, noting that most controllers are secured with two 10mm bolts torqued to approximately 6-8 ft-lbs. If the controller is hardwired rather than plug-and-play, carefully cut each wire 3-4 inches from the connector to allow room for splicing the new controller. Set the old controller and mounting bracket aside for proper disposal or recycling. Clean the mounting surface with a dry cloth to remove any dust or corrosion before installing the new bracket.

Step 3: Install New Brake Controller Bracket

Position the Tow-Ready Brake Controller Bracket in the same location as the original, ensuring it’s level and won’t interfere with pedal operation or driver legroom. Align the mounting holes and insert the bolts, hand-tightening them first to verify proper fit. Torque the bolts to 6-8 ft-lbs using a calibrated torque wrench, being careful not to over-tighten as this can crack the bracket. Verify that the bracket is stable by applying firm downward pressure—there should be no flex or movement. Once secured, mount the Tekonsha Prodigy P3 Brake Controller or Hopkins Agility Brake Controller onto the bracket using its integrated mounting points, typically secured with two smaller screws torqued to 3-4 ft-lbs.

Step 4: Connect Brake Wiring and Connectors

Reconnect the positive (red) and negative (black) power wires to the corresponding terminals on the new brake controller, ensuring connections are tight and corrosion-free. If splicing is necessary, strip ½-inch of insulation from each wire end and use the Butt Splice Connector Kit (18-14 AWG), crimping firmly with a proper crimper tool and covering with Electrical Tape. Connect the 7-Pin Round Connector + Plug to the controller’s output terminal, which will interface with your Alliance Avenue 32RLS trailer’s brake system. Verify the pinout matches your trailer’s specifications—pins 1 and 5 typically carry brake signal, while pins 2 and 7 are ground. Secure all wires with clips or ties to prevent vibration-related loosening, maintaining at least 6 inches of clearance from engine heat sources.

Step 5: Program Controller Sensitivity Settings

Reconnect the negative battery terminal and power on the brake controller by turning the ignition key to the accessory position. Access the controller’s dial or digital interface and set the gain/sensitivity to the middle position as a baseline for your Alliance Avenue 32RLS—most trailers respond well to settings between 4-6 on a 10-point scale. Check your travel trailer’s owner’s manual for any specific brake gain recommendations, as heavier trailers may require higher settings to engage properly. Allow the controller to fully initialize, which typically takes 30-60 seconds on first startup. If your controller has a manual vs. proportional mode, select proportional mode for smoother brake response that mirrors your tow vehicle’s braking pressure.

Step 6: Inspect Trailer Brake System Components

Connect your tow vehicle to the Alliance Avenue 32RLS using the 7-Pin Round Connector, ensuring the connection is fully seated and the locking collar is hand-tight. Visually inspect all visible brake lines and wheel cylinders on the trailer for leaks, cracks, or fluid seepage—any found should be addressed before testing. Check brake fluid level in the trailer’s brake system reservoir if accessible; it should be near the full mark with no cloudiness or debris present. Verify that the trailer’s breakaway switch and safety cable are properly installed and functional, as these are critical safety components. Ensure all lug nuts on trailer wheels are torqued to manufacturer specification, typically 85-100 ft-lbs for standard RV applications.

Step 7: Test Brake System Operation and Performance

Drive to an empty parking lot or controlled testing area and perform a series of low-speed brake tests, starting with gentle application to verify brake engagement. Press the brake pedal with moderate pressure and listen for a clicking or humming sound from the trailer, indicating the brake controller is sending signal to the trailer brakes. Gradually increase braking pressure and speed, noting any pulling or swerving—the trailer should brake evenly without dragging to either side. If brake response feels inadequate, stop safely and increase the controller’s gain setting by 1-2 increments, then retest. Perform a final high-speed test from 25-30 mph with firm braking pressure to confirm smooth, responsive braking with no trailer sway or jackknifing.
