[To] what does [the conductor with insulation of color] black from the key switch get hooked to on an enternal [not sure if this is meant to be "external" or "internal"--please clarify] wiring harness going to 1995 FORCE 40-HP outboard engine if the key switch is a Quicksilver Mercury push-to-choke [model that has] wires not terminals on the key switch?

In most wiring of 12-Volt DC circuits, a conductor with black insulation is part of the battery negative circuit. This generally does not vary by the manufacturer, horsepower, or model year of an outboard engine, or by the manufacturer or model of a replacement ignition switch, or if the switch has conductors as pigtails insted of terminals. However, it is never a good idea to deduce the function of a circuit's conductor entirely by the color of the conductor's insulation. The best way to verify the circuit is to obtain the original wiring diagram for the outboard engine and its wiring harness, and to study the replacement part you have obtained to see if it is compatible.
