The speed sensor is a simple magnet based hall effect sensor. It stikes to magnets across each other and sends a pulse out. Both wires are the same. What is your guage asking for?
The Temp sensor is a 0-5volt.
The range is
-40F =5v
260F = 0v
So within that range the sensor will read.
What does your temp guage require?
Gas Gauge? I am stumped, always wanted to get into the workings of the signal wire, never found the time.
