CURT Manufacturing 4-Pin Flat Connector Plug-and-Play T-One CURT 56127 Custom-Fit Trailer Wiring Harness for Mitsubishi Outlander

Add trailer lighting capability to your 2011-2013 Mitsubishi Outlander or 2012-2013 Outlander Sport without cutting a single wire. CURT part 56127 is a vehicle-specific T-one connector harness that taps directly into your factory tail light wiring, delivering a clean, reliable 4-pin flat connection at the rear of the vehicle.

Stop Splicing -- Start Towing

Generic wiring kits require you to cut into your vehicle's tail light circuits, risking shorts, blown fuses, and voided warranties. The CURT 56127 uses a T-one converter design that plugs inline with the factory tail light connectors -- no splicing, no soldering, no guesswork. The harness routes neatly to a standard 4-pin flat trailer connector that hangs at the hitch receiver ready to plug into any standard trailer or bike rack lighting system.

CURT engineered this harness specifically around the 2011-2013 Mitsubishi Outlander and 2012-2013 Outlander Sport tail light wiring architecture. The plug locations, wire lengths, and routing path are all matched to these vehicles, so installation is straightforward even for a first-timer with basic hand tools.

No-Splice T-One Design

Plugs inline with factory tail light harness connectors. No wire cutting or soldering required for a clean, reversible install.

4-Pin Flat Output

Standard 4-pin flat trailer connector provides running lights, brake lights, and turn signals to any compatible trailer, bike rack, or cargo carrier.

Vehicle-Specific Fitment

Custom-molded connectors match the exact Mitsubishi Outlander tail light plugs -- no adapters needed, no rattling loose over time.

Converter Circuit Included

Built-in converter handles vehicles that use a combined brake/turn signal circuit and translates it to the separate brake and turn signal wires trailers require.

What Signals Does It Carry?

The 4-pin flat connector on the CURT 56127 carries the four standard trailer lighting functions:

  • Pin 1 (White): Ground
  • Pin 2 (Yellow): Left brake/turn signal
  • Pin 3 (Green): Right brake/turn signal
  • Pin 4 (Brown): Running/tail lights

This covers the legal lighting requirements for most open utility trailers, boat trailers, small enclosed trailers, folding camping trailers, bike racks with lighting boards, and cargo carriers with lights. It does not carry electric brake output or auxiliary 12V power -- those require a separate brake controller and 7-pin connector system.

Plug-and-Play Installation
Most owners complete the CURT 56127 install in under 30 minutes. Access the tail light assemblies, unplug the factory connectors, insert the T-one harness inline, route the output lead to the hitch area, and you're done. No test light probing or wiring diagrams required.

Where This Fits in the CURT Trailer Wiring Lineup

CURT's T-one connector harnesses (the 5-digit part numbers in the 56000 range) are vehicle-specific plug-and-play solutions. They sit above universal splice-in kits in terms of installation ease and below CURT's powered 5-pin and 7-pin converter harnesses in terms of trailer capability. The 56127 is the correct T-one harness for these specific Mitsubishi model years -- other Outlander years use different part numbers due to tail light connector changes.

Verify Your Model Year Before Ordering
This harness fits the 2011, 2012, and 2013 Mitsubishi Outlander and the 2012 and 2013 Mitsubishi Outlander Sport. The 2014+ Outlander received a tail light redesign and requires a different CURT part number. Check your door jamb sticker for the exact model year.

Common Applications

  • Small utility and cargo trailers (lighting circuit only, no brake controller)
  • Boat trailers and personal watercraft trailers up to the vehicle's tow rating
  • Hitch-mounted bike racks with integrated lighting boards
  • Folding camping trailers and pop-up campers (if no electric brakes required)
  • Cargo carriers with running light requirements
Maintenance Tip
Apply dielectric grease to the 4-pin flat connector before each season and after any washing. The connector end is exposed to road spray -- a light coat of grease prevents corrosion that causes flickering or dead trailer lights.
Tow Rating Reminder
This wiring harness does not increase your vehicle's tow rating. Always observe the 2011-2013 Mitsubishi Outlander factory tow rating (up to 3,500 lbs with properly equipped vehicles -- verify in your owner's manual for your specific drivetrain). The harness provides lighting signal only and is not related to structural towing capacity.

Important Information -- Read Before Installing
  • This harness is designed for the 2011-2013 Mitsubishi Outlander and 2012-2013 Mitsubishi Outlander Sport only. Using it on other years or models may result in connector mismatch or incorrect wiring function.
  • The 4-pin flat connector does not support electric trailer brakes. If your trailer has electric brakes, you need a 7-pin connector system and a separate brake controller.
  • Do not exceed the harness amperage ratings. Connecting high-draw LED light bars or multiple trailer lighting circuits through this harness can damage the vehicle tail light circuit.
  • Always verify that trailer running lights, brake lights, and turn signals are functioning correctly before towing on public roads. Inoperative trailer lighting is a traffic violation in all U.S. states.
  • Towing capacity is determined by your vehicle's manufacturer, not by this wiring harness. This product provides electrical connection only and has no effect on structural tow ratings.
  • If your Outlander has aftermarket tail lights or a prior electrical modification, verify factory connector compatibility before installing.
