To run the factory gauges you will need you factory pcm. Do not hook up anything from the factory PCM to your BS3. I run the factory gauges with the stock PCM and my BS3 runs the engine.

What I did was leave the temp sensor,oil pressure sensor,altenator wiring hooked up and removed all the rest of the wires that were in charge of running the motor. So that way the remaining wires in the ECU were still wired up to the dash. If you removed everything you need to get a pinout chart and go from there to get everything back to run the factory gauges.
