The sixteen-foot Mercury 8-pin boat side wiring harness from Buckshot Racing #77 is a quality-grade control harness engineered for seamless electrical integration between your Mercury outboard motor and the driver’s cockpit or console.
 
This marine-grade wiring harness serves as the vital electrical conduit that links the engine's powerhead systems to the dash-mounted controls, offering superior performance, reliability, and compatibility across a broad range of high-performance and recreational watercraft.
 
Designed specifically for Mercury outboard motors, this 16-foot marine wiring harness includes the standard Mercury 8-pin male connector on the engine side, ensuring secure and precise connectivity to the powerhead harness.
 
This critical interface supports all necessary engine functions, transmitting essential signals for tilt and trim control, ignition switch power, starter relay activation, primer functionality, overheat temperature warning, tachometer signal, and engine alarm circuits. These features are crucial for both performance diagnostics and real-time engine management.
 
On the console end, the harness is terminated with color-coded wire leads that are compatible with a wide variety of marine key switches, dashboard gauges, and control panels. These leads are designed to integrate with aftermarket or OEM marine switches and indicators, giving boat owners the flexibility to customize their cockpit setup while retaining full functionality of all engine systems.
 
Additionally, the harness supports panel-mounted tilt and trim switches, allowing precise control directly from the helm.
 
This 8-pin boat wiring harness is a direct replacement for aging or damaged Mercury factory harnesses. It is ideal for use in performance applications such as drag race boats and tunnel hulls, as well as for recreational setups including runabouts, ski boats, fishing boats, and bass boats.
 
The boat-side harness is constructed using marine-grade wire and corrosion-resistant terminals, ensuring durability in harsh saltwater and freshwater environments. Its robust construction helps prevent electrical failures caused by moisture, vibration, or temperature extremes.
 
Whether you're upgrading your existing marine electrical system or restoring a vintage Mercury-powered vessel, the 16' Mercury 8-pin boat side wiring harness provides dependable connectivity, optimal signal integrity, and ease of installation.
 
This wiring solution is an essential component for any Mercury outboard control system, delivering the precision and reliability that high-performance boating demands.
