Temp Sensor Lead

Hello. I just joined this site, but I have read previous topics and I admire everyone's level of knowledge and appreciate their willingness to help. My question shows my limited knowledge about some pretty basic stuff. I need to know what type of wire connector is needed to connect to my Chrysler engine's temperature sender. I have seen new gauge sets with a screw stud and washer/nut setup, buy mine looks more like a flared nipple. It sort of looks like a trumpet at the end. Also it looks like it was painted over so I assume I am going to have to scrape the paint off at least the end. From the Chrysler manual on this site it almost looks like the female side of a spade connector is used, but the picture is fuzzy. Any help is greatly appreciated.

Thanks! That's what I gathered from the picture in the manual, but when I try to zoom in it looks like a blob. Should I try and tape/fasten this somehow or just let friction do its thing?

No wiring harness. In fact that is going to be my biggest next challenge. Only the Speedo, volt meter and oil pressure gauges work. No wires going to fuel sender, temp sender or tach. In fact, I'm not really sure where the tach sender is. No anchor light wiring either. I'm focusing on the temp gauge right now as I was helping a friend with a boat at a marina and a couple mechanics mentioned that the temp gauge is the only one they really pay attention to. Thanks for your help. I am going to go with the spade connector and crimp as needed. Cool boats by the way! That Atom Skier must turn some heads and I know the work that must have gone into restoring that wood boat. I looked long and hard at a couple wood Resorters. That trailer is the best.
