This jinyi unit is built as a direct-fit substitute for common Mercury part numbers and model years from 1994 onward that use side mount control boxes. It combines corrosion-resistant materials, a molded waterproof base, and a six-wire harness to match Push-to-Choke wiring schemes so you can replace the old switch quickly without cutting or repinning factory wiring.\u003c\/p\u003e\n\n\u003ch3\u003eWhat makes this jinyi ignition switch compatible with my Mercury outboard?\u003c\/h3\u003e\n\u003cp\u003eThe switch is designed to match the electrical layout and mounting of Mercury part numbers 87-88107A8, 87-88107A5, 87-88107, and 7-1155, so it integrates with many models from 1994 and later that use side-mount control boxes. It uses a 6-wire configuration to support Off, Ignition, and Start positions including Push-to-Choke setups.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect-fit replacement for the listed Mercury part numbers.\u003c\/li\u003e\n  \u003cli\u003ePre-wired harness avoids cutting or splicing factory cables.\u003c\/li\u003e\n  \u003cli\u003eThree-position Faceplate: Off → Ignition → Start functionality.\u003c\/li\u003e\n  \u003cli\u003eDesigned for side-mount control box installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the six-wire design improve starting and controls?\u003c\/h3\u003e\n\u003cp\u003eThe optimized 6-wire layout separates starter, ignition, choke, and accessory circuits to mirror OE wiring and reduce misfires or hard-to-turn keys.
