I hooked up an external tach to adjust my carb this past weekend. You need to hook the green wire up to the blue wire that comes from the ignition coil. If you look at the ignition coil it's the bottom left clip. I didn't have the proper clip to piggy back off the wire so I just stripped back a little of the wire's covering and clipped the green wire on. Obviously, take the black wire and ground it to an engine bracket or something, but not the negative terminal on the battery. A technician told me that soldering the clip to the wire was the best bet, but just clipping it on with the aligator clip worked fine for me. Hope this helps.

don't we already have a tach in the car?

Yeah, but it's nice to have it right there under the hood next to the carb while you're adjusting it. It gets it just right.
