LOW CURRENT CONNECTIONS
All logic and low power connections are through a single 35-pin AMPSEAL connector (mold in
the cover) utilizing gold-plated pins. e matching AMPSEAL receptacle’s wire silos come sealed
by a membrane. Pierce the membrane by inserting the individual 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 AMPSEAL sealing plug. Do not mix gold
and tin pin types.
• Figure 4 shows the AMPSEAL receptacle (plug) housing. Note the molded-in silo numbering.
• Figure 5 illustrates the connection assignments (as the plug aligns with the controller).
• Table 2 lists the matching AMPSEAL vehicle-harness component part numbers.
