Help With Tachometer

[Jan Eyerman <jan.eyerman@usa.net>]

I just bought an Alpine IV positive ground tach for my '62 Hillman Minx.  How
is it wired?  Where does the connection on the Lucar (push on type) connector
go and where does the odd little screw on connector go?  

Thanks,

(for those of you interested, the Tach is going to replace the very large
"triple" gauge instrument) and the temperature gauge is an Alpine unit going
into the clock hole (with an adapter))
