They solder to the wire and also have heat shrink as part of the connector.
So if you use them your connection is soldered and also moisture proof.
Napa carries them.

Don't like them. Several sensors in these cars, like the throttle body and MAF are fraction voltage signal systems, and ANY change in the resistance in the harness can throw the system off, which causes no end of problems. Simply strip off a short length of clean wire on each end, twist around each other, and solder. Afterwards heat shrink tubing will complete a fully weather tight connection without any difference in resistance.

We have repaired dozens of these cars this way, never had an issue; but nearly every one we have seen with any kind of crimp connectors in the harness has had issues, which were immediately solved by the soldering method above. It simply works.

I wonder if it is the small amount of metal in the connector that causes the resistance??
I have done it many times the way you describe, but also countless times I have forgotten to slide the heat shrink tubing on before soldering
