4.
Turn off the ignition and remove the ignition
key. Maintain control of ignition keys while work
is performed. Attach a notice “DO NOT USE” to
the ignition switch in order to avoid activation of
the systems or starting of the motorhome.
5.
Block wheels to prevent movement.
6.
Locate and remove the black, vinyl wrapped
access panel found to the left-hand side of the
steering column, at floor level, see Figures 1
and 2.
7.
In the area behind where the panel was
removed, locate the OEM keyless entry
connection near the steering column. It will
be a 16-pin Packard connector with cavities
A through D populated with the remaining
positions empty. The harness will have a tag
labeled “FCCC Body Builder Interface” near
the connector and contain Circuits 088, 089,
705, and 706. See Figures 3-5 for clarifying
information.

Once the correct connector and harness has been
located, remove the wire loom and any tape from the
harness approximately 6-8” from the connector in
order to locate the diode connecting Circuit 089 (bluewhite wire) to Circuit 053 (blue wire). See Figure 6.
9.
If Circuit 053 (blue wire) has already been
disconnected from the diode, take a clear photo and
attach it to a draft claim. Submit using the inspectiononly code listed on Page 4. If the Circuit 053 is still
connected to the diode, proceed to the “Correction”
procedures, Steps 10-14.

CORRECTION
10. Double check the circuit numbers and then cut
Circuit 053 (blue wire) approximately 1” away from
the diode. Refer to Figure 7.
11. Wrap both ends of the cut wire with 5 rounds of
electrical tape to completely cover any exposed
wires. See Figure 8.
12. Place the harness back into the wire loom and wrap
several times with electrical tape.
