Hey Ice Man, gotcha!
Sometimes it's easier to point out what is necessary (and let people figure out it's NOT there) than to just say NO and have a long discussion about why it won't work.
For those that didn't get it, the PCM uses crank and cam sensors to determine when to fire a pair of coils. It also reports on the data line to the instrument cluster what the RPM is. There is no TACH signal or wire per se to connect an aftermarket tach. The cam sensor output would be the closest, but it's 5 volt signal isn't what the tach could use anyway. That's why a driver is needed. Here is one description.
