I hooked mine up to the white wire going to the guage cluster. It is also the same white wire coming off of the tach filter in the engine bay.

The tach filer is located right next the ignition module and coil. There is a white wire coming off of the tach filter and goes to the guage cluster for the tach. You can tap into this wire in the engine bay on the tach filter, or you can pull the guage cluster and tap into the main harness going to the cluster.
