1968 mercury outboard wire harness cypher?

The wire harness that goes to the control box! I figured out all but two. Red is +, Blue/Bla is -, gray is chock, yellow is start, White not in yous, But brown and org/pink what are they for so I can wire it currently. Other note one of them goes to a blue mount along the red blue white terminals. I like to believe the other ends up being a 8 gauge red wire. And what do the re white a blue stand for. Both the engine and wire harness appear to be stock.
