Does anyone know what the pin layout is for the 4 pin connector on a speedohealer as pictured below? I need to take a feed off the speed sensor input for my power commander. Instead of getting the tank up and checking at the sensor I'm trying to save time by figuring out which cable in the 4 pin plug is which. My speedohealer is under the back seat with the PCV so it's only a 5 minute job if I know which pin is which in the speedohealer. The 4 cables should be speed input, speed output (back from the healer ecu), +12v and GND. Thanks in advance.
