The Engine-Side Harness (Mercury OEM Part Number 96220) features an 8-pin connector that links the outboard motor’s electrical system to the boat’s control panel. 
 
For those maintaining or upgrading their Mercury 2-Stroke V6 outboard, a reliable engine-side harness (96220) is essential for optimal performance. We offer three alternatives for the engine-side harness: 1) Buckshot Racing #77, 2) CDI Electronics, and 3) Mercury OEM harnesses.
 
These options ensure compatibility with a wide range of Mercury Marine, Mariner, and Mercury Racing outboards from 135 HP, 150 HP, 175 HP, 200 HP, 220 HP (2.4), 225 HP (2.5), Carb 245 HP, 260 EFI, 280 ROS, S3000, SST-120, and 300 HP Drag, including both carbureted and electronic fuel injection (EFI) models.
 
Designed for legacy Mercury 2-stroke 2.0L, 2.4L, and 2.5L powerheads, these harnesses support both standard and high-performance applications, including offshore and ROS models.
 
They serve as direct replacements for aging or damaged 8-pin wiring harnesses and are compatible with Mercury models such as 135 HP, 150 HP, 175 HP, 200 HP, Black Max, XRI, XR2, XR4, XR6, 200 ProMax, 220 HP Laser, 225 HP Pro Max, 245 HP, 260 EFI, 280 ROS, and 300 Drag.

These harnesses are designed for easy installation while maintaining the integrity of the electrical system.
 
They feature essential connections such as the rectifier wire, which links to the 12V starter solenoid to convert AC power into DC for battery charging and electrical system operation.
 
The power-to-key switch connection ensures proper engine start/stop functionality, while the ground to the dashboard provides stable readings for gauges.
 
The starter wire connects the key switch to the solenoid, allowing the engine to engage upon ignition.
 
The primer wire plays a role in the fuel enrichment system, assisting with cold starts.
 
Additionally, the tachometer wire transmits RPM data to the dashboard for monitoring engine performance.
 
The temperature sensor wire relays engine temperature data, while the temperature horn alert wire activates an audible warning if the engine temperature exceeds safe levels.
 
With multiple female 8-pin harness options available, Buckshot Racing #77, CDI Electronics, and Mercury OEM harnesses offer high-quality solutions tailored to your specific needs.
 
Replacing an outdated Mercury female 8-pin 87266, 96220, or 6220A4 wiring harness ensures the electrical system functions reliably, extending the life of your Mercury 2-Stroke outboard.
