first off, it down work like say any 1980 jeeps
the cluster is like your computer monitor
the cluster, is a digital , display that uses serial communications
data, from the PCM to present to you, all data (gauges)
this is all done over a 2 wire, transmission line.
called CCD.
via pins 1 and 2.
the PCM monitors all sensors, not the cluster like days of old.
then The PCM sends data to the cluster brain
the cluster then shows you the data.
that is how it works, 93 to now.
