THE 35-PIN AMPSEAL CONNECTIONS
All logic and low power connections are through a single 35-pin AMPSEAL connector integrated into
the cover utilizing gold-plated pins. e matching receptacle’s wire silos come sealed by a membrane.
Pierced the membrane by inserting the individually terminated wires. To maintain the IP65 rating,
use the proper wire gauge and insulation thickness. Seal any non-used wire positions that have their
silo-diaphragm pierced with the specic seal plug.
• Figure 3 shows e AMPSEAL receptacle (plug) housing and silo numbering.
• Table 1 lists the matching vehicle harness components.
• Table 2 lists the individual 1351 System Controller inputs and outputs characterizations, by
pin number, including the associated VCL functions and diagnostic Monitor variables.
