I made some up last night. I do actually have a pretty good iron...one with the dial base and all. I usually use 700-750 degrees. My biggest problem was no way could I get all of the deans 12 gauge wire in there. I had to strip off some of the wire to get it to fit with NO solder on it. In the end I used MetalMan's method. I flux'ed the heck out of the wire and connector then I inserted it into the connector leaving a small amount of wire exposed on top, then I applied heat and solder, it made a very nice joint, solder flowed into the connector and I couldn't pull it apart. I then put two layers of shrink and called it a day. I do feel like maybe using 14 guage wire may be a better move as no stripping would be needed. I may make some new one's up with the 14 ga stuff later.

Thanks guys.
