It's just a 1/4" male spade post on the sender. A 1/4" female spade is all Toyota uses for the harness, it's just the insulation part that's different. I wouldn't hesitate to use a standard spade here. The insulation part on most of my vans has deteriorated, but as long as the conductor part is intact, I keep using the factory harness connector. If you really want a factory type connector here, you could probably go to a salvage yard and cut one off multiple places on many different makes/models, then solder/shrink tube. Tim
