yes they should heve them, I think they're 0.177" insulated bullet connectors. Yos should also find them at the chain auto parts stores. GB makes quality connectors, you can get them in-bulk through the big box home improvement stores too. NAPA also has them.
I was getting erratic H2O temp readings, & found my female lead to the sender by the H2O filler neck was corroded, & cleaning it caused it to ring-off in my hand, so it probably was about to break entirely anyways at the fitting crimp. Replaced w/just the fitting you are searching for. I crimp it twice, next-to one-another. Sometimes I solder the connection.
If you are looking for the male/female spade terminals, w/the bent 'keeper' for the nylon plugs, you can probably find them at the same places, but you have to go to an auto parts store most-likely, or an appliance repair shop if there's one close to you. They both use the same types of connectors w/that little bent piece you have to release w/a small pick or shim, from one side of the fixture or the other. Look for the additional square or rectangular space above or below the male or female spade, that will be the side you have to stick the pick or shim into & wiggle it to get the bent tab to release the terminal as you pull on it. Sometimes it takes some fiddling, don'y yank it or you will probably snap the wire. When the bent 'tang' releases, the terminal will practically fall right-out.
