It was a PITA to wire up, SARD provided a detailed installation manual, with pictures, that was 75% incorrect, we ended up having to trace all of the connections down using the shop manual during installation. For the sensors, we used an oil filter sandwich adapter (oil temp, pressure), and a water temp sensor adapter, spliced into the coolant return line.
Once configured, its a great display, all necessary info readily visible, logical warnings, and very configurable... I regret not picking up the ST8110SR (same cluster, but with integral boost), but at the time, I wasn't willing to pay $800 more just for boost functionality; now, my boost gauge is part of the CarPC, which makes it a little less convenient.
