Trust me that you'll have a far better crimp using the uninsulated butt connectors (uninsulated terminals period) using FAR LESS pressure - over the insulated versions... and all the shrink tube I use is GLUED type. So moisture is never an issue as well as it provides the strain relief at the connection.

I've take a few factory OEM harness apart to piggy back a Fast ECM in. The OE do use solder on the harness. Some times its 2 or 3 wires going into one wire they use a crimp and then solder over it.
