X2. I always soldered my pins after crimping. Just youse a small amount of solder, too much and you can't get the pins into the bodies. Also get the weatherpack extractor tools, you will not be able to get the pins out for repair without one.I don't know the prices at Pegasus, but we get all of our weather pack parts and wiring supplies from Del City.

Trick with proper soldering is the minimal use of heat and material. You don't want the solder to wick past the wire end of the connector. It will make the wire brittle.You need to be careful soldering wires. If a soldered wire is allowed to move around during service there is a good chance the wire will break inside the insulation and can be very difficult to track down. You should use some type of strain relief such as several layers of shrink tubing or tied in a bundle so it can’t bend.
