There is a metal connector with a hook. The wire is crimped into the connector. That is inserted into the large end of the plastic piece with the curved part of the metal connector pointed down toward the solid plastic bar on the mouth of the connector.
What is the secret to inserting the metal connector until it seats? Mine goes in about 1/2 way and stops not engaging the metal bar in the plastic piece
I have crimped thousands of these and have found the insulation is usually what is holding up the insertion of the contact into the housing. Stripping a little further back helps but I am not fond of that because of corrosion that develops on the bare conductor behind the contact.
When we developed the RP for NTRAK, we found that the 12 ga landscape cable’s insulation was thicker than normal. We tapered it down with an exacto knife so that the contact would slide into the housings. It is a PITA, but works quite qell. Anderson also makes removal/insertion tool that helps push the contact in. I have used a small jewelers screwdriver to push them in.
The tool looks a lot like the wood carving tool I used. 4 out of 4 – I could not insert it with finger pressure. It was 14 ga wire and it was not the insulation either. Once they are together they work well.
