The Tekonsha Brakeman IV digital trailer brake controller provides safety and connection when you need it most. As a time-based controller, the Brakeman IV is a great choice for basic, light-duty towing needs. This compact controller works by electronically connecting your vehicle and your trailer. When you hit the brakes in your tow vehicle, it generates an output signal that ramps up, or increases over a period of time, applying braking power to your trailer at a fixed rate. The Brakeman IV has up-front buttons so you can easily adjust power output, the sync ? or aggressiveness with which the controller applies the brakes, and engage manual override to help you brake safely when an unexpected stop pops up. It also works with electric or electric over hydraulic braking systems, and features advanced internal circuit protection, real time comprehensive diagnostics, and short circuit protection. Because the Brakeman IV is a time-based controller, there?s no requirement that it be positioned in the direction of travel; it can be installed anywhere you like as long as it is within reach of the driver. Plus, the Plug & Play feature allows for quick and easy connection with your vehicle?s wiring. The Brakeman IV trailer brake controller works with1-4 axle trailers, comes with all the mounting hardware needed for installation, and is backed by a limited lifetime warranty.

Tekonsha is a leading manufacturer of electronic trailer brake controllers, pioneering the category in the 1970s. The lineup spans proportional units such as the Prodigy P3 and Prodigy iD, time-delayed controllers, the wireless Prodigy RF, plus vehicle-specific wiring harnesses, adapters and trailer brake components engineered for smooth, predictable stopping at any speed.
Tekonsha Engineering Company began in 1964 building RV steps and mirrors. Within a few years it had found its real calling, and by the 1970s Tekonsha was pioneering the manufacture of electronic trailer brake controllers, the product category that still defines the brand. More than half a century later it remains the reference name in trailer braking and is part of the Horizon Global group alongside Reese, Draw-Tite, Fulton, Bulldog and Wesbar.
A brake controller is the component that tells a trailer's electric brakes how hard to work and when, and getting that right is the difference between a controlled stop and a shove from behind. Tekonsha builds both major types. Proportional controllers use an internal accelerometer to sense how quickly the tow vehicle is slowing and apply trailer braking to match, so light braking stays light and hard braking is immediate. Time-delayed controllers ramp to a preset output over a fixed interval, a simpler and more economical approach that suits occasional towing.
The current brake controller range covers most of that ground. The Prodigy iD pairs with a phone through Tekonsha's EDGE technology for setup and monitoring, the P3 offers storable settings for multiple trailers and a trilingual colour LED display, the Prodigy P2 adds a dimmable display and boost mode for heavier loads, and the Voyager keeps operation simple and dependable. The Prodigy RF mounts to the trailer itself and controls wirelessly, which suits rental fleets and drivers who swap tow vehicles.
Installation is supported by vehicle-specific brake control harnesses that plug into a factory connector rather than requiring cut-and-splice wiring, along with mounting brackets and adapters. Matched controller bundles pair a unit with the correct harness. Products are tested to meet and often exceed published industry standards.

The 2004-2017 Volkswagen Touareg Tekonsha Brakeman IV Time Delay Brake Controller for Trailers with 1 to 4 Axles Black 8507120 (Part #8507120 70367) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Tekonsha Electronic Brake Control is an electronic trailer brake controller designed for 2, 4, 6, and 8 brake applications. It allows the driver to control trailer brakes independently from the tow vehicle's brakes using a dashboard-mounted control unit. The system includes an Output (Gain) Control to set maximum brake power, a Sync Control to adjust brake aggressiveness, and a Manual Control slide for independent trailer braking. The digital display shows gain settings and helps with setup and troubleshooting.
The package includes: (1) Brake Control Unit, (1) Mounting Bracket, (4) Mounting Screws, and (1) Warranty Card. You will need to supply separately: 10 Ga. wire, a 30 Amp auto-reset circuit breaker, assorted ring terminal and butt connectors, and 4" cable ties (6-10 pieces).
The control is designed for 2, 4, 6, and 8 brake applications. The manual does not specify which trailer models or manufacturers are compatible, or any vehicle-specific fitment restrictions. Contact the manufacturer at 1-888-785-5832 or www.tekonsha.com for compatibility with your specific trailer and tow vehicle.
Required tools are: assorted end wrenches, a drill with a 1/8" bit, a wire connector crimp tool, a probe type circuit tester, a wire cutter/stripper, and a screwdriver or 1/4" nut driver. The manual does not specify whether professional installation is recommended or required.
You must use 10 Ga. wire and a 30 Amp auto-reset circuit breaker. These are critical for safe operation and must be supplied separately; they are not included in the package.
The control must be mounted in a location that meets three criteria: (A) the unit must be mounted securely to a solid surface, (B) the unit must be easily reached by the driver, and (C) the area behind the mounting location must be clear so nothing will be damaged when drilling. The manual shows it can be mounted under the dash, on top of the dash, vertically, or at any angle, but you must verify the area behind is clear before drilling.
1. Determine a suitable mounting location that is solid, easily reached, and has clear space behind it. 2. Hold the mounting bracket in the selected position and mark hole locations through the slots in the bracket. 3. Using a 1/8" diameter drill bit, drill holes at the marked locations. 4. Secure the bracket in place using the 2 self-tapping screws provided with a screwdriver or 1/4" nut driver; be careful not to strip the holes by over-tightening. 5. Mount the brake control unit to the bracket using the remaining 2 self-tapping screws as shown in the illustration.
You must drill 2 holes with a 1/8" diameter (1/8" dia.) bit at the locations marked through the bracket slots. Before drilling, ensure the area behind the panel is completely clear to avoid damaging anything behind the mounting surface.
The brake control uses four wires: Black (Vehicle Power), Red (Stop Light), White (Vehicle Ground), and Blue (Trailer Brakes). The black wire connects to vehicle power, the white wire to vehicle ground, the red wire to the stop light circuit, and the blue wire to the trailer brake circuit. Correct wire identification and connection is essential for proper operation.
A 30 Amp auto-reset circuit breaker is required. This must be installed in the power circuit to protect the system. The circuit breaker is not included and must be supplied separately.
Preliminary setup requires: (1) Connect the trailer and press and hold the brake pedal; the display will show the Gain setting. Adjust to approximately 2.0 by pressing the Gain button up or down. (2) While still holding the brake pedal, press either Sync button; the display will change to Sync setting. Adjust to 4° by pressing the Sync button (+ or –) as necessary. Then perform a test drive in an open area like a large parking lot to fine-tune the settings.
In an open area such as a large parking lot: (1) Drive forward and apply the trailer brakes using the Manual Control. (2) If trailer brakes are weak, adjust the Output (Gain) Control up. If brakes jerk or lock up, adjust it down. Repeat until firm braking is felt without jerking or lockup. (3) Once Gain is set, drive forward and press the brake pedal; the tow vehicle and trailer should make a smooth stop. (4) If the stop seems slow and more aggressive braking is desired, push the Sync Up (+) button while holding the brake pedal. If too aggressive, press Sync Down (–). (5) Make several stops at various speeds and adjust Sync until stops are smooth and firm. Slight adjustment of Output (Gain) may also be desirable.
The Output (Gain) Control establishes the maximum amount of power available to the trailer brakes. As Gain is increased, more power will be available to the brakes when the brake pedal is pressed or the manual control is used. The Gain setting is shown on the digital display as 0 through 10, with 0 being minimum and 10 being maximum. Adjust the Gain during initial setup, when trailer load changes, when different trailers are used, or to adjust for changing road conditions. Increase Gain if brakes are weak; decrease it if brakes jerk or lock up.
The Sync Control adjusts trailer brake aggressiveness. The trailer brakes become more aggressive as the Sync '+' button is pressed. The Sync setting is shown on the display as 0° through 9°, with 0° being the least aggressive and 9° being the most aggressive. To view the Sync setting, press the brake pedal (trailer must be connected) and press either the + or – Sync button. The Sync adjustment has no effect on the Manual Control. Adjust Sync for individual driver preference or changing road conditions. During test drive, if stops seem slow, push Sync Up (+) while holding the brake pedal; if too aggressive, press Sync Down (–).
The Manual Control is located on the front of the Brake Control Unit at the right side. It applies only the trailer brakes and is used during initial setup and in situations where it is desirable to reduce speed slowly. When the Manual Control is moved to the left, it begins to apply the trailer brakes. The further left it is moved, the harder the brakes are applied until the maximum setting by the Output (Gain) Control is reached. The Gain setting will be shown on the display and can be adjusted when using the Manual Control. The Manual Control activates all trailer stoplights. Note: Some tow vehicles' stoplights may also activate.
The digital display shows the Gain setting when the control is activated. It is used to setup and monitor the Brake Control and can be used when troubleshooting. The display shows different information depending on the situation: a single decimal point when control is activated with no trailer connected; the Output (Gain) setting when control is activated with trailer connected; and the Sync setting when the brake pedal is pushed with Sync Control activated and trailer connected. The display can also show error codes such as OL (short in blue wire circuit) or Er (internal brake control problem).
Yes. Light pressure on the brake pedal will activate the trailer's brakes with no effect on the tow vehicle's brakes. This is useful for gradual slowing on steep grades or before stops.
On some vehicles, operating the Brake Control's Manual Control will not disengage 'Cruise Control'. If this is a concern with your vehicle, consult your vehicle's manual or the brake control manufacturer at 1-888-785-5832.
When towing with hazard flashers on, the digital display will flash with the hazard flashers. If the brake control is set aggressively, pulsing may be felt in the trailer brakes. Installation of a Pulse Preventor will isolate the brake control from the flashers and eliminate the flash/pulse situation.
Yes. Periodic adjustment of the Sync and Output controls may be necessary to correct for changing road conditions, trailer loading, brake wear, and/or driver preference. Monitor braking performance and adjust as needed to maintain smooth, firm stops.
This indicates no power to the control, no ground, reversed black and white wires, or a blown circuit breaker. Check and repair all connections. Verify that the black wire (vehicle power) and white wire (vehicle ground) are correctly connected and not reversed. Check that the 30 Amp auto-reset circuit breaker has not blown. Refer to the wiring section of the manual.
This indicates no connection or incorrect connection at the stoplight switch, or a blown fuse in the stoplight circuit. Check and repair all connections to the stoplight switch. Verify the red wire (stop light) is correctly connected. Check the stoplight circuit fuse in your vehicle. Refer to the wiring section of the manual.
This indicates the red wire (stop light) is connected to the wrong side of the stoplight switch or to the wrong switch (such as cruise control). Check and repair all connections. Verify the red wire is connected to the correct stoplight switch terminal. Refer to the wiring section of the manual.
This indicates the brake control unit is miswired. Check and repair all connections. Refer to the wiring section of the manual to verify all four wires (black, red, white, and blue) are connected to the correct terminals.
This indicates a short circuit in the blue wire circuit (trailer brakes). Locate and correct the short in the blue wire. Check for damaged insulation, pinched wires, or incorrect connections in the blue wire circuit.
This indicates an internal brake control problem. Return the unit to the dealer for evaluation. Do not attempt to repair the unit yourself.
Several causes are possible: (1) No connection between the brake control and brakes—confirm the blue wire is connected to the trailer connector and check the connector terminal positions. (2) Miswired trailer connector—confirm the trailer connector terminal positions are correct. (3) Short or overload in the trailer brakes—troubleshoot the trailer brake circuit per the brake manufacturer's instructions. (4) Internal brake control problem—return the unit to the dealer for evaluation.
Two causes are likely: (1) Miswired trailer connector—check and correct the connector wire positions. (2) Output (Gain) setting too low—increase the Output (Gain) Control. Start by checking the trailer connector terminal positions, then perform a test drive and increase the Gain setting until firm braking is felt without jerking or lockup.
This indicates the trailer connector is miswired. Check and correct the connector wire positions. Verify that the blue wire (trailer brakes) is connected to the correct terminal on the trailer connector.
The control is designed for 2, 4, 6, and 8 brake applications. The manual does not list specific trailer models or manufacturers. Contact Tekonsha at 1-888-785-5832 or www.tekonsha.com to confirm compatibility with your trailer and tow vehicle.
You must supply: 10 Ga. wire, a 30 Amp auto-reset circuit breaker, assorted ring terminal and butt connectors, and 4" cable ties (6-10 pieces). The bracket, mounting screws, and control unit are included.
Yes. You must drill 2 holes with a 1/8" diameter bit to mount the bracket. Before drilling, ensure the area behind the panel is completely clear to avoid damaging anything behind the mounting surface.
Set the Gain to approximately 2.0 and the Sync to 4° during preliminary setup. Then perform a test drive in an open area and adjust both settings until you achieve smooth, firm braking without jerking or lockup.
Use 10 Ga. wire and a 30 Amp auto-reset circuit breaker. These are critical for safe operation and must be supplied separately.
Yes. Light pressure on the brake pedal will activate only the trailer brakes with no effect on the tow vehicle's brakes. This is useful for gradual slowing on steep grades or before stops.
This occurs when the brake control is set aggressively and hazard flashers are on. Install a Pulse Preventor to isolate the brake control from the flashers and eliminate the pulsing.
Yes, the 3072-037 is designed for Volkswagen, Audi, and Porsche vehicles. However, the brake control connector location varies by brand: Volkswagen connectors are located either under the dashboard or behind the lower kick panel near the emergency brake pedal; Audi connectors are centered behind the dashboard between the steering column and radio; Porsche connectors are behind the dashboard on the right side of the steering wheel. Consult your vehicle's specific section in the manual for exact location.
You will need: test-probe, trim panel remover, 8mm socket, and Torx 20 driver.
The manual requires that the vehicle be off with the keys removed from the ignition before beginning installation. While the manual does not explicitly state to disconnect the battery, you must always read, understand and follow all warnings and instructions printed on the tow vehicle's battery.
Always wear safety glasses and use all safety precautions during installation. Do not pinch or cut wires when reinstalling trim panels. Do not exceed the lower of the towing manufacturing rating (including in your vehicle owner's manual) or the specific amperage ratings stated on the product. Always read, understand and follow all warnings and instructions printed on the tow vehicle's battery.
The 3072-037 is an Electric Trailer Brake Control Wiring Adapter designed for Volkswagen, Audi, and Porsche vehicles. It connects to the vehicle's electric brake control harness connector to enable trailer brake control functionality. The adapter must be plugged into the vehicle's mating brake control connector, and all brake control manufacturer's installation instructions must be followed after installation.
On Volkswagen vehicles, the brake control plug can be located either under the dashboard or behind the lower kick panel near the emergency brake pedal. If under the dashboard, remove two Torx T20 screws under the lower dash panel and pull down the dash panel to locate the mating 4-pin connector wrapped in grey foam tape. If behind the kick panel, remove the lower kick panel and door sill as needed to locate the mating connector wrapped in grey foam tape.
On Audi vehicles, the brake control connector is located centered behind the dashboard between the steering column and the radio. To access it, locate and remove two 8mm bolts under the dash panel, then remove the two small trim panels on each side of the steering column. The mating brake control connector is wrapped in grey foam tape.
On Porsche vehicles, the brake control mating plug is located behind the dash panel on the right side of the steering wheel, wrapped in grey foam tape.
If the connector is under the dashboard, remove two Torx T20 screws under the lower dash panel. If the connector is behind the kick panel, remove the lower kick panel and door sill as needed. The mating connector in both locations is wrapped in grey foam tape.
