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 2021 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the 2012-2021 Mercedes-Benz Sprinter Tekonsha Voyager Proportional Brake Controller for Trailers with 1 to 4 Axles Black 9030 (Part #9030 70243) is designed to fit the 2012-2021 Mercedes-Benz Sprinter.
The 2012-2021 Mercedes-Benz Sprinter Tekonsha Voyager Proportional Brake Controller for Trailers with 1 to 4 Axles Black 9030 (Part #9030 70243) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The N9030 is an electronic brake control designed specifically for use with electric trailer brakes on trailers with 2, 4, 6, or 8 brake applications. It activates by inertia, sensing deceleration and generating an output that reflects the inertia sensed. It can be controlled manually via the slide knob or automatically via the tow vehicle's brake pedal.
No. The N9030 is specifically designed for use with electric trailer brakes only. It is not compatible with surge brakes or other brake types.
The brake control must be mounted between -20 degrees nose down and 70 degrees nose up. Failure to install within these constraints may cause the control to become inoperable.
The control includes #6 x 3/8" screws for bracket mounting. Do not use longer screws or drill additional holes, as this may damage the unit.
Drilling is not required if you use the supplied #6 x 3/8" screws in the existing mounting holes. However, drilling or using longer screws may damage the unit and is not recommended.
Reversing the connection to a breakaway battery on the trailer will destroy the brake control. Ensure correct polarity before connecting.
No. You must disconnect the trailer plug from the tow vehicle prior to testing a breakaway switch, or you may destroy the brake control.
Power should never be set high enough to cause trailer brakes to lock up. Skidding trailer wheels can cause loss of directional stability of the trailer and tow vehicle. Set power to a point just below wheel lockup or at sufficient force to achieve maximum braking power without locking.
The bi-colored light shows: GREEN when the trailer is connected (normal standby state), and RED when the brake pedal or manual slide knob is activated and the trailer is connected. The light may also show orange shades during level adjustment. The GREEN light draws only 5 milliamperes of current from the tow vehicle—it would take over 10,000 hours to drain the tow vehicle battery.
No. Do not mount or activate RF generating items such as cell phones or two-way radios within 12 inches of the brake control, as they may interfere with its operation.
Mount the bracket securely to a solid surface. The mounting surface must be rigid enough to support the control and maintain its angle within the -20 to +70 degree range during operation.
Tighten the #6 x 3/8" screws until snug. Do not over-tighten, as this may damage the unit. The screws should be tight enough to prevent movement but not so tight as to strip the threads or crack the mounting holes.
After securely mounting the bracket, you must set the level adjustment. Connect the trailer to the tow vehicle (the bi-colored light should glow GREEN), set the power knob to maximum by rotating it fully clockwise, then depress the tow vehicle's brake pedal and hold it while adjusting the level knob.
1. Connect trailer to tow vehicle; the light should be GREEN. 2. Set power knob to maximum (fully clockwise). 3. Depress and hold the tow vehicle's brake pedal. 4. Rotate the level knob counter-clockwise (toward the back) until the light starts to change from GREEN to RED. 5. Carefully rotate the level knob clockwise (toward the front) until ORANGE appears. The light should show DIM ORANGE for typical, BRIGHT ORANGE for aggressive, or DIM RED for more aggressive settings. 6. Release the brake pedal. The trailer and tow vehicle must be parked on a level surface during this procedure.
The range of adjustment for the level knob from DIM ORANGE to DIM RED is 20 degrees of rotation.
1. Connect trailer to tow vehicle. 2. Set power knob to 12 o'clock position. 3. Drive on a dry, level paved surface at 25 mph and apply the manual slide knob. 4. If trailer brakes lock up, turn power down (rotate counter-clockwise toward 8 o'clock). If braking is insufficient, turn power up (rotate clockwise toward 5 o'clock). 5. Repeat until power is set just below wheel lockup or at sufficient force for maximum braking. 6. Make low-speed stops using the brake pedal to verify power and level adjustments. Automatic braking is initiated and terminated via the stoplight switch.
Yes. Always warm the trailer's brakes before setting the power. Warm trailer brakes tend to be more responsive than cold brakes. To warm them, drive a short distance (1/4 mile) at 45 mph with the manual lever engaged enough to cause trailer braking at a low level.
Fine tuning is done after power has been set. Make several slow (25 mph) stops as if coming to a stop sign and observe how the trailer brakes respond. If brakes grab too much (aggressive setting), rotate the level knob clockwise toward you. If the trailer tends to push the tow vehicle (delayed setting), rotate the level knob counter-clockwise away from you. Repeat until desired trailer braking is achieved.
When the brake control is leveled properly, there will be very little current flowing through the brake magnets in a static state with the foot pedal depressed. The brake magnets will hum when there is current flowing through them. Anytime the bi-colored light shows any color other than GREEN, there is current flowing through the brake magnets. Additionally, when power is set correctly, you should feel unified braking between the trailer and tow vehicle.
The level adjustment is critical because it determines whether the automatic braking response is delayed or aggressive. Improper level adjustment causes the braking response to be too harsh or ineffective. The brake control is activated by inertia and requires the level to be set properly, or braking response will be compromised.
GCWR is the Gross Combined Weight Rating—the maximum combined weight of the tow vehicle and trailer. The GCWR must never exceed the vehicle manufacturer's recommendation. Exceeding this rating can compromise braking performance and vehicle safety.
The N9030 is activated by inertia. It senses deceleration and generates an output that reflects the inertia sensed. In a stationary state, the brake control will not apply the trailer brakes unless the manual slide knob is actuated. When the tow vehicle is moving and the brake pedal is depressed, the stoplight switch signals the control to apply trailer brakes proportional to the deceleration sensed.
If the tow vehicle is connected to the trailer but there is no GREEN light, check for: 1. Corrosion on the trailer plug contact—clean if necessary. 2. Loose POWER or GROUND connection—verify all connections are tight and secure.
If the trailer is connected and the light is GREEN but no RED light appears when the manual slide knob is activated, the probable causes are: 1. POWER set at or near minimum—increase power setting. 2. Short on BRAKE line (BLUE wire)—check for damaged wiring. 3. BLACK and WHITE wires reversed—control may be destroyed. 4. 12 volts from external source on BRAKE line (BLUE wire)—check for interference.
If the light is dim RED or flashing RED when the manual slide knob is activated, the probable causes are: 1. Open on GROUND line (WHITE wire)—check for broken or disconnected wiring. 2. Short on BRAKE line (BLUE wire)—inspect wiring for damage or pinching.
If the light glows dim RED and becomes brighter as the power knob is decreased, the probable causes are: 1. Short on BRAKE line (BLUE wire)—check for damaged or pinched wiring. 2. Defective brake magnets—the control may need replacement.
If braking with the foot pedal is too aggressive, the probable causes are: 1. Sensor set too aggressive—adjust the level knob clockwise (toward you) to reduce aggressiveness. 2. Power set too high—reduce the power setting by rotating the power knob counter-clockwise toward the 8 o'clock position.
If braking is delayed for an extended period, the probable causes are: 1. Sensor set improperly—refer to the leveling sensor section and re-level the control. 2. Power set too low—increase the power setting by rotating the power knob clockwise toward the 5 o'clock position.
If the trailer is connected, the light is GREEN, but no RED light appears when the brake pedal is depressed, check: 1. Vehicle not moving—the control requires vehicle movement to apply brakes via the brake pedal. 2. No signal from brake light—test voltage on the RED wire. 3. Sensor set improperly—refer to leveling sensor section. 4. Bad connection on RED wire—verify all connections are secure. 5. Blown stoplight fuse—check and replace if necessary.
Trailer brakes should be adjusted after the first 200 miles of operation when the brake shoes and drums have "seated," and then at 3,000 mile intervals, or as use and performance requires.
1. Jack up the trailer and secure it on adequate capacity jack stands, following the trailer manufacturer's recommendations. Check that wheels and drums rotate freely. 2. Remove the adjusting hole cover from the adjusting slot on the bottom of the brake backing plate. 3. With a screwdriver or standard adjusting tool, rotate the starwheel of the adjuster assembly to expand the brake shoes until the wheel is very difficult to turn. 4. Rotate the starwheel in the opposite direction until the wheel turns freely with slight lining drag. 5. Replace the adjusting hole cover and lower the wheel to the ground. 6. Repeat on all brakes. Never crawl under the trailer unless it is resting on properly placed jack stands.
For drop spindle axles, a modified adjusting tool with approximately an 80 degree angle should be used instead of a standard adjusting tool.
When adjusting trailer brakes: 1. Jack up the trailer and secure it on adequate capacity jack stands following the trailer manufacturer's recommendations. 2. Never lift or support the trailer on any part of the axle or suspension system. 3. Never crawl under the trailer unless it is resting on properly placed jack stands. 4. Verify that wheels and drums rotate freely before and after adjustment.
If you are unsure about the proper setting procedures, review the steps starting at "Leveling the Sensor" through "Fine Tuning," or consult the tow card included with your brake control. You can also contact Tekonsha for technical assistance at 1-888-785-5832 or www.tekonsha.com.
Yes. The front of the brake control must be horizontal, and the control must be parallel to the direction of travel. This orientation is necessary for proper sensor operation and accurate inertia sensing.
Yes. The power may need to be adjusted for different load weights and road conditions. After initial setup, you may need to fine-tune the power setting depending on how heavily the trailer is loaded and the road conditions you encounter.
Not all trailer brakes will lock up due to various conditions. However, inability to lock up the brakes generally indicates the need for an inspection to determine the cause. This may indicate worn brake linings, improper brake adjustment, or other mechanical issues with the trailer brake system.
The 3030-037 Electric Trailer Brake Control Wiring Adapter is designed for Mercedes Sprinter vehicles. However, your vehicle must be equipped with an OEM trailer tow package, which includes a green 4-pin connector located under the driver side seat. If your Sprinter does not have this connector, the adapter will not be compatible.
Vehicles not equipped with an OEM trailer tow package will not have the green 4-pin connector. If your Sprinter lacks this connector, the 3030-037 adapter cannot be installed. You should verify with your vehicle's documentation or a Mercedes dealer whether your vehicle includes the OEM trailer tow package before purchasing this adapter.
You will need: a trim panel remover, a Philips screwdriver, and wire cutters.
Removal of the driver side seat may be required to access the green 4-pin connector located under the seat. The manual notes this as a possibility but does not state it is always necessary. You should first attempt to locate and access the connector without removing the seat; if you cannot reach it, seat removal will be needed.
1. Turn off the vehicle and remove the keys from the ignition. 2. Locate the green 4-pin connector under the driver side seat (you may need to remove the seat to access it). 3. Plug the brake control adapter into the vehicle's electric brake control harness connector. 4. Follow all brake control manufacturer's installation instructions for routing and mounting the unit. 5. Perform test procedures as instructed by the brake control manufacturer. 6. Replace all parts removed during installation and ensure all fasteners are reinstalled in their original positions.
Yes. The 3030-037 is a wiring adapter only. You must follow all installation instructions provided by the electric brake control manufacturer, including how to mount the unit, route the adapter to exit the bottom of the dash, and perform test procedures. The adapter simply connects your vehicle's electric brake control harness to the brake control unit.
The maximum amperage rating is 24 amps, which corresponds to a maximum of 4 axles and 8 brakes. However, you must not exceed the lower of either the towing manufacturer's rating (as stated in your vehicle's owner's manual) or this 24 amp specification. Exceeding this limit can cause fires.
Always wear safety glasses during installation. Read and understand all warnings and instructions printed on the tow vehicle's battery before beginning. Follow all warnings and instructions included with the adapter purchase. Do not exceed the amperage ratings stated on the product or in your vehicle's owner's manual, as overloading the circuit can cause fires.
The vehicle must be off with the keys removed from the ignition before you begin installation.
You must replace all parts removed during installation and ensure all fasteners removed are reinstalled into their original positions.
Yes, the 3030-037 is designed for Mercedes Sprinter with OEM trailer tow package. Your vehicle must have a green 4-pin connector under the driver side seat. Vehicles without the OEM tow package will not have this connector and cannot use this adapter.
You need a trim panel remover, Philips screwdriver, and wire cutters.
The maximum is 24 amps (4 axles, 8 brakes). Do not exceed the lower of this rating or your towing manufacturer's rating, as overloading can cause fires.
