Hello All,

Black wire pictured below- a ground for.....? Timing? Maintenance? Thoughts on what to do w/ this wire (leave it alone or cap it)? Mercury 5.7 2-barrel out of a 97 crownline- engine serial 0K031298 if that matters.

Mercury doesn't have my service manual available- so any help would be appreciated. Thanks!
