4-Flat Trailer End Conne ctor 8ft Jacketed Cable

The REESE 4-Flat Trailer End Connector with 8ft Jacketed Cable (part number 787268) is the standard wiring harness for towing applications requiring SAE J560 four-pin flat connector compatibility. This connector type manages brake and tail light circuits for trailers, utility carriers, and towed equipment across a wide range of vehicle platforms. The 8-foot length accommodates most common trailer-to-vehicle mounting geometries without requiring extension harnesses.

The jacketed cable design protects individual conductors from UV degradation, moisture intrusion, and abrasion—critical for vehicles regularly exposed to harsh environmental conditions. At 0.95 lbs and compact dimensions (7.4 × 1.45 × 11.75 inches), the harness stores easily and handles routing through tight firewall and frame passages. The four-flat connector configuration remains the most widely supported trailer light standard across domestic and imported trucks, SUVs, and towing-rated sedans, making this harness a universal solution for brake light synchronization during towing operations.

This harness is essential for operators maintaining recovery vehicles, patrol units, or personal transports that regularly tow enclosed trailers, equipment carriers, or boat trailers. Vehicle-to-trailer brake light continuity prevents traffic safety violations and eliminates the liability exposure of non-functional brake indicators during operation. The REESE brand's positioning in OEM-specification connectors and heavy-duty aftermarket towing ensures compatibility with factory wiring harness expectations on most North American vehicles manufactured within the last two decades.
