red w/white looks like it goes to the cruise module? that could work as well, likely at 2,000 pulses per mile.
37% is a LOT of time spent injecting fuel for being at idle/such low of a load. if injector flowrate were to remain what it is at idle, then you could only inject a little less than 3X as much fuel at full output than at idle..... that doesn't seem very likely with what i remember about diesels.
