Proper crimp tool. Had issues with that type too. I think this is the correct tool: D-Sub Pin Crimper -

I just had to figure this out.

Strip the wire, lay it in the left side of those connectors and crimp the edges around it with some small needle nose. Seems to work best if you end up crimping down on some shielding as well so dont strip the wires too close.

Edit: actually, those look a bit different from the ones I just did for my GM IAT. Gotta be similar though.

I've got two of the "real" ones. They've got a ratcheting type action. I've got a bunch of the pins and connectors like are pictured too.

Anyone need a loaner program?

Usually with these type of pins there is one proper (and very expensive) crimp tool, and a variety of not quite right crimp tools (with subtly wrong dies) which will work but probably won't produce a robust connection. For anything that is critical I suggest soldering to the crimp pins rather than using the wrong tool.

Yeah, those look similar to the IAT sensor pins. Not having the correct crimper I just used needlenose pliers to crimp it to a mechanically sound condition, and then soldered it. Those little rubber grommets help seal the connector and also provide some strain relief, so make sure the wire you use fits pretty snugly inside them.

The RadioShack D-sub tool (actually, any D-sub tool) is way too small to crimp those pins. You'd be better off using needle-nose pliers and putting a dab of solder on it.

If you have a crimp tool rated for use with Molex 062 pins, that one is almost perfect for these. Mine's an actual Molex-brand ratcheting tool (and it was a couple hundred bucks) but it does an excellent job. The better tools have a multi-level die that crimp the stripped portion and the insulated portion in a single operation, and put a proper little foldover in the crimp ends. Cheaper versions are available that do the main and relief crimps in multiple steps.

This One looks like it might do the job, though I've never tried it.

If you're going to do a small volume of weatherpak pins and want an OK tool, get This One. It's not awesome, but it's cheap and it'll work.
