Most of those OEM grommets are still available from the (st)dealer. There are very good push on/ring terminals available aftermarket. Some have shrink tube seals on them.  Check out some of the offerings from McMaster Car. Most of the parts store crimp stuff is garbage.

Subject: OEM rubber covered waterproof crimpon connectors

Where can I get the oem style of rubber covered connectors that cam on the starter and fuel pump?
It seem stupid to use non waterproof ones. I am having problems with 5 year old connectors and the originals lasted 25 years.
thanks
