You have to run a wire from the PCM to the tach. It's pin 46 IIRC, it's a white wire with a black stripe, you have to run it to the larger multiplug on the left, to pin 8. Some cars have a green wire near the under-dash fuse box you can use. Do a quick search, I know there's a couple threads about this.

Just have to run the wire to the middle connection of the tach on the back of cluster itself.
