Engine Harness Connector

Connection to the engine is provided by a Deutsch/TE 21 pin connector (part number HDP24-24-
21PE). The mating connector is Deutsch/TE part number HDP26-24-21SE.)

.

6.2.3

Sealed Connectors

The provided Deutsch sealed weather-proof plug includes a locking ring device which must be turned

counter clockwise to separate the connectors. To positively seat the connectors the locking ring is
turned clockwise.

LOFA does not recommend using dielectric grease or sealant with sealed
connectors. These chemicals may cause seal damage and allow water
entry. Use LOFA provided cavity plugs to seal the connector if wires are
removed.

6.2.4

Unsealed Connectors

For unsealed connectors exposed to the elements, LOFA recommends using dielectric grease to
protect contacts.
