The assembly uses 12 AWG and 16 AWG pure copper conductors, tin-plated brass terminals and a nylon wire loom to resist corrosion and abrasion. Designed for straightforward splice-in installation, it supplies power for taillights, turn signals, brakes, reverse lights and auxiliary circuits needed for trailers and towing accessories.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this harness match my vehicle's factory USCAR 7-way socket?\u003c\/h3\u003e\n\n\u003cp\u003eThe Oyviny harness is manufactured to OEM-style USCAR dimensions so it plugs directly into standard vehicle-side male 7-way connectors. Color-coded wires follow common trailer-wiring conventions to make splicing into your vehicle wiring simple and reliable. Terminals are tin-plated brass for consistent electrical contact across weather exposure.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eOEM-style USCAR 7-pin socket profile for direct compatibility\u003c\/li\u003e\n  \u003cli\u003eColor-coded wires for quick identification during splicing\u003c\/li\u003e\n  \u003cli\u003eTin-plated brass terminals to resist corrosion\u003c\/li\u003e\n  \u003cli\u003eFits many Ford, GM, Chevy, Dodge Ram, Toyota models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and protection keep the connector durable?\u003c\/h3\u003e\n\n\u003cp\u003eDurability comes from a combination of pure copper conductors and a protective nylon flex tubing loom. The wiring uses 12 AWG for heavier circuits and 16 AWG for standard lighting circuits, giving both conductivity and mechanical strength. The nylon tubing helps shield wires from chafing, road debris and moisture, extending service life in towing environments.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e12 AWG and 16 AWG pure copper conductors for strong conductivity\u003c\/li\u003e\n  \u003cli\u003eNylon wire loom for abrasion and moisture protection\u003c\/li\u003e\n  \u003cli\u003eDurable molded socket housing resists impact and heat\u003c\/li\u003e\n  \u003cli\u003eCompact 16-inch length for tidy routing behind bumpers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is it to install and what tools or parts are included?\u003c\/h3\u003e\n\n\u003cp\u003eInstallation is splice-in style: cut out the damaged harness or tie into existing wiring and crimp or solder the matching color-coded wires. The package includes six nylon terminal connectors to help secure the splices and provide a more finished connection.
