need recommendation for tool to proper 'seat' wires in this connector type

[sanman]

Can anyone recommend/point me to the proper type of tool to properly 'seat' the wires into these types of connectors?

Thanks for the help!

That is called an IDC (insulation displacement connector). The proper tooling is called a "punch-down tool".
You need a tool with the proper sized blade for the connector, which differs between manufacturers. You will need to identify the model of connector to find it.
For example, for Amplimite HDE connectors you can use the TE 91287-1 tool, which is a very basic manual tool. Other types of tool may have spring assist, wire cutters, or levers or automatically index the connector as you insert wires.

Thanks Helius. Based on your information. I will do some research and see what I can find

That looks very much like a TE MTA-series connector (or clone) to me. Measure the pitch between the two pin centers: 0.1" (2.54mm) would be MTA-100, while 0.156" (3.96mm) would be MTA-156 (picture attached).

Following helius's good advice, here's the official punchdown tool for MTA-100:

MTA-156:

Rather expensive for what they are, but you may be able to find them for a few dollars cheaper through other distributors.

If you're only doing one or a few connectors, rather than buying the proper expensive tool, I've used a back side of a butter knife or a thin flat bladed screwdriver to carefully push the wire into the connector. Just make sure what you use isn't so wide that it spreads the two halves of the connector and you end up with a poor contact.
