RMC plug
Yellow wire
with black trace
(Y/Bk)
In this case, it is the
yellow wire with black
trace. Probing it with a
DVOM should yield:
1. Continuity to
ground when the
seat is empty
2. Continuity to
ground when the
PTO is ON and the
brake is released
If there is continuity at
other times, there is a
short.
If 1 or 2 are not true,
there is a fault.
