Product Description
Mercury Quicksilver 84-865770A02 is a 12-inch (305 mm) power-trim adapter harness. It connects an older power-trim pump with a three-blade connector to a newer remote-control harness with a three-pin Packard connector.
Key Features
- 12-inch / 305 mm harness
- Molded three-pin female to Packard three-pin female adapter
- For the older-pump to newer-control-harness conversion
Installation Notes
Disconnect battery power before working on the trim wiring. Compare both connectors and their pin arrangements, then secure the harness clear of heat and moving parts. Check trim operation after installation.
