Need help wiring a starter solenoid

[Criderdaddy]

Hello all, I’m new here but have been getting a lot of knowledge and decided to join. I have a 1976 Mercury Thunderbolt 50hp that I’m replacing the internal wiring harness. Can someone tell me where these three wires go in correlation to the attached pic? Thank you

Always best to provide a serial number for those of us looking can have a better idea of where to look

This is boatinfo and has many of the service manuals, need adobe flash player

Thank you very much. I’m guess the orange goes to the screw below that’s hard to see that also has a connector from the mercury switch that I believe kills the engine on too much tilt.

I'm unable to find the number, but since BT has the other wires covered, in most cases the orange (for Mercury) goes to the changing system (alternator or such) which is connected direct to the battery positive. Check if the place your talking about does connect the the bat
