so these MC have 2 CTS, 1 for the ecu and 1 for the gauge, does any one know if both theses sensors are 2 wire or 1 wire? i believe the ecm 1 is a 2 wire, but not sure of the gauge sensor, both are mounted very close to each other in front of the carb, 1 ontop of the thermostat housing and the other just beside it.
