Tekonsha 3030 Brake Controller Harness | Sprinter 2012-2021 Plug & Play
Plug-and-play Tekonsha brake controller harness designed for select Sprinter tow-package vehicles. Connects compatible Tekonsha controllers without cutting or splicing.
Overview
This Tekonsha vehicle-specific harness is built to connect a compatible Tekonsha brake controller to the factory brake-control port in select Sprinter applications. It is a clean solution for buyers who want a factory-style connection instead of hardwiring. For the right vehicle, this harness helps speed up installation, reduces wiring guesswork, and keeps the brake-controller setup neat and serviceable.
R&P Service Insight
Brake controller harnesses save time only when the vehicle-side plug is confirmed first. On Sprinter-based rigs, chassis details matter more than the RV brand name.
- Buy by Chassis: Confirm the actual tow vehicle chassis and model year before ordering.
- Buy by Connector: This harness depends on the OEM factory connector being present.
- Buy by Controller Port: Best for compatible Tekonsha Plug & Play controllers such as Prodigy models.
R&P Knowledge Hub
Compatibility: Fits select Freightliner Sprinter 1500 and Mercedes-Benz Sprinter applications as listed below.
Vehicle / System Fit: Brake controller to OEM tow-package port connection for Sprinter-based towing.
Installation Notes: Verify vehicle has the OEM tow package and the green 4-pin connector under the driver-side seat before ordering.
Performance Insight: A vehicle-specific harness keeps installation cleaner and avoids unnecessary cutting and splicing of factory wiring.

R&P Repair Insight
The fastest way to miss on this harness is shopping by coach brand alone. Many motorhome brands use multiple chassis platforms, so physical verification is required.
- Connector Check: Look for the green 4-pin connector under the driver-side seat.
- Tow Package Check: Vehicles without the OEM tow package will not have the matching plug.
- Fitment Check: Confirm your exact Sprinter model and year against the fitment table below.
