Yamaha Conventional Main Harness – 10-Pin, 19.7 ft (688-8258A-60-00)

Wiring gremlins ruin more weekends than bad weather. Swap that sun-brittled loom for this factory 10-pin harness and bring every circuit on your Yamaha back to factory spec in one shot. At 19.7 feet (6 m), the “-60” version stretches easily from the transom of a 23-footer to the helm, carrying clean power, trim signals, and warning-horn voltage through tinned-copper conductors wrapped in tough PVC jacketing. A twist-lock engine plug with a molded rubber boot seals out spray, while the dash end terminates in color-coded pigtails that match the service manual—no guess-and-splice drama.

Why riggers choose the genuine 688-8258A harness:

• 10-pin round connector fits all 1994-up conventional Yamaha outboards—40 hp to 250 hp, two-stroke or four-stroke.

• Pre-loomed gauge leads for tach, trim, and oil lights eliminate messy junction bars.

• Double-lip weather seals and locking collar keep corrosion out of delicate pins.

• SAE-grade tinned wire resists salt, vibration, and 105 °C under-cowling heat.

Whether you’re re-powering a classic skiff or chasing an intermittent trim fault, drop in this plug-and-play harness and get back to worrying about tides—not voltage drops.
