There should be 3 leads on your tachometer: +12VDC, Ground, and Signal.
Signal goes to that Tach connector on the distributor cap.

Thanks Ken. I'll have a closer look at the connector area with a mirror - is there an illustration somewhere as I don't see a tang there, is it a socket that takes a plug pehaps?
<EDIT> Ok I had a look at google images and I can see there's a tang underneath. I'll pick up a GM plug and hook it up to the green wire on my tach.

Anyone like to comment on my idle rpm's in park and drive mentioned above? Are those numbers OK?
