iam a little lost on how the serial data wire works. do you just tie the rpm and water temp to the grey serial data wire, lost with the water temp gauge also because theres not a wire for it i dont think. Also i do have a 3 wire coolant sensor with a pig tail off it for the gauge

The Serial Data wire sends digital info to the guages, ... It carries multiple signals... You cannot "tap into" the Serial Data wire from say a ECT sending unit and expect the guage to work. If your guages are looking to a different pin for the ECT, then you can run a wire from the sending unit (sensor) to the gauge cluster.
