​Description
Background
The original sleeper control panel 12V power port is no longer available. New 12V power ports are available from a
new supplier. The new 12V power ports are compatible with the control panel, but the electrical connectors are
different. This change requires a jumper harness to combine the original power port harness to the main sleeper
harness.
Obsoleted 12V power port part numbers:
• 18-02859 – Power Port
• 17-02745 – Bezel
Procedure
Please follow your dealership's safety procedures and precautions to ensure the vehicle can be safely repaired
and maintained.
To replace the electrical side for the new Casco power port:
1. Cut the harness for the old power port 15mm behind the protective insulation on each side using a wire
cutter/crimper.
2. Insert both ends of the harness into a butt-splice connector, attaching the respected circuits between the two
harnesses: RED6953-1, ORN6120-3, and WHIT1130-5.
3. Crimp both sides of the butt-splice connector, then heat shrink the butt-splice connector until it is snug around
the wire.
