Here we have a full length factory wiring harness w/key switch for 1980s thru 1990s era Mercury outboards- it has the 8 pin wiring connector, and the 3 pin style connector for trim and tilt. The harness is in good condition- a few of the loose wiring ends look like they have non-factory ends spliced on- so be advised there. Overall though, this is a good candidate for re-use. It should not take much to adapt it to a new application. See pics!
