I cannot find a manual or wiring diagram showing where the wires coming out of my 1959 merc mark 35a go to.

Wires at motor harness that i'm unsure about are 1-solenoid, 2-choke, 3-magneto, and 4-rectifier. I know where the positive and negative cables go

Do i use a 5 pole push-to-choke switch?

Well, they sold me a switch for 1977-1995 Evinrudes and Johnsons.

It has an "M" terminal (stop circuit)
It has a "B" terminal (non-switched B+)
It has another "M" terminal (ground)
It has an "A" terminal (switched B+)
It has a "C" terminal (primer)
It has an "S" terminal (start circuit)

Is this correct? "M" = magneto. "B" = battery. "M" = ground. "A" = ???... "C" = choke. "S" = solenoid.
If not.....HELP!!!

Thanks.

Yes, I think the a terminal is a switched positive that was used for accesories or a electric shift on OMC

So this looks correct then? I just don't want to fry anything!
