Starting with a modular, have a couple of questions.

Thanks, John. Mine are all closed ends, too. I updated the post below to link to the closed end parts. What are the little covers called? I'd like to get some for myself.

Cheers,
Brian

There are two kinds of covers. The 'normal' ones that Synth Tech and pretty much everyone else uses are called 'dust covers'. There are also 'strain relief covers too'.

In general I like shopping Digikey first because they have a much more detailed drill down filtering system when searching for parts plus they usually list associated parts etc. which I think is very helpful.

Here is a 4 pin MTA 0.156 24 gauge connector on Digikey:

Note that near the bottom of the page there is a section called "Associated Product" which listes the covers. Here's one you may want:
