Dielectric Grease Application

Before following these instructions, refer to excluded connec-
tor types (See Exclusions below).
1. Use dielectric grease in a tube for larger connection
points or apply with a syringe for small connectors.
2. Apply dielectric grease to the female contact (fill it
approximately ½ full; see example below)
3. Leave a thin layer of dielectric grease on connector face.
4. Assemble connector system immediately to prevent
moisture or dust contamination
5. Pierce one of the unused wire seals before assembly if
the connector system tends to trap air (i.e. AMP Seal)
and then install a seal plug.

Deutsch HD, DT, DTM, DRC Series

The Deutsch connector system is commonly used for harsh
environments. Follow installation instructions.

AMP Seal

The AMP Seal connector system is used on Control ADE Plat-
form and Ground Modules.
Apply dielectric grease to the female contact. If trapped air
prevents connector from latching, pierce one of the unused
wire seals.

After assembly, install a seal plug (JLG #4460905) to keep out
moisture. Seal plugs may also be installed by the wire harness
manufacturer if an unused wire seal was damaged during
assembly.
