In my manual, it shows two tools. One that reads pulse-
codes, the other that reads on/off percents (a meter).
Can I fab both of these? The code reader looks like
an LED, switch and resistor (if I had the schematic)
simply wired in a fancy box. The on/off reader a plain
voltmeter (12v scale?) What functions are the pins in
the X-92 and X-11 connectors?
Or if they are inexpensive (riiiight!) can I buy them
from MB or after market?
