Not sure how to source a tach on a newer motor. I'd google the specific motor wiring diagram, it will show which wire from the ECU sources to the Tach. The same is true for engine temp, oil pressure, etc. If that isn't available, Water Temp, Oil Temp and Pressure, and Volts are all fairly easy. Mishimoto (and many many others) make an inline sensor for your radiator hose. They work great and are very simple to install. I'd also look into a oil filter sandwich plate. From there you can tap oil pressure and temp sensors.
