REMOVAL
CAUTION: Do not remove the grease from the
S B E C 60-way connector. The grease is used to pre-
vent moisture from contacting the connector termi-
nals. Ensure that at least a 1/8 inch thick coating of
grease covers the bottom of connector cavities. If
not, apply a liberal coating of Mopar Multi-Purpose
Grease to the connector prior to connecting it to
the SBEC.
