you have 2 'negative' wires on the coil... on the three wires going in, the two on either side are trigger signals. Keep in mind, since we have a waste spark system, your shift light will consider your car to be a 2 cylinder, so if you can't adjust the tach accordingly, you will need to buy a tach adapter.

There are some threads that allude to being able to use a ECM pin out (I don't remember the number just now) but I wasn't able to get that to work when hooking up a similar tach driven device.
