What do you mean by ect? Is that basically the throttle position sensor for electronic throttles? And with the O2 sensors, will I have problems with running an exhaust system that consists of just headers, extensions just long enough to have an O2 sensor bung and have a V band flange welded on, mufflers, and exhaust tips, probably ending just around the back of the cab with no crossover pipe. At this point, oil temp would probably only be for control of the fan on the oil cooler
