35 convertible sedan electrical harnesses

[32Bee]

I've begun the installation of my car's electrical harnesses and have a question or two. I'm finding it difficult to push each bullet end into the special connections that were provided with the system. I'm concerned that I'm not
pushing each bullet end far enough into the inner metal connector. I tried
sliding the outer rubber sleeve off of a connection in order to properly view if
the bullets were in far enough but the rubbers are so tight it's not doable. My
second question is should I be using a small amount of silicon dielectric on the
bullets prior to installation into the metal sleeves? It seems to me that would
also make it significantly easier to achieve a tighter connection.
