17.13. Top left, D-shape: Yellow wire with Black trace:
• Behavior: Should have continuity to ground
when seat is empty or the PTO is ON and the
brake is released.
• Circuitry: The black wire with yellow trace splits
into two yellow wires with black traces, and
enters a second 8-pin connector (pigtail) within
6" of the 8-pin connector at the module.
17.14. From the other side of the 8-pin pigtail connec-
tor, it emerges as one yellow wire with a black
trace, and a second yellow wire with a white
trace. See Figure 17.14.

17.15. Check the PTO and seat safety circuits with the
8-pin pigtail connector unplugged, then recon-
nect it and continue with the RMC plug test.

• Behavior: When the female pin terminal leading
into the main harness is probed, there should be
continuity to ground only when the seat is empty.
• Circuitry: The yellow wire with white trace leads
to the forward terminal on the seat safety switch,
where it finds a path to ground when the seat is
empty.
• Interpretation: If behavior is correct, the seat
safety circuit is good.
If there is continuity to ground when the seat is
occupied, the switch may be inoperative, or
there may be a short to ground in the wire lead-
ing to it. If there is not continuity to ground when
the seat is empty, the switch may be inoperative
or there may be an open condition in the wire
leading to it.
