Clean 12v switched source that is hot cranking and running

I have to be missing something. The black/pink wire appears to power the heater (this is called ACC2 in the above linked diagram) while the 14 ga black wire (ACC1) between the blue and yellow wire appears to power the radio and horn. So they both should be hot during run. This means I probably need to retest those because it only makes sense that they are both hot in the run position.
