Temperature sensor

[Cissco]

Does anyone know where to get a temperature sending unit for a 91 1/2?stupid me ordered one from Geno's garage for a '89 through '91 not realizing it doesn't fit my '91 and a half. Well it fits but the gauge instantly pegs the hot with a cold engine. The one they list for the 92 and up has a total different plug. The part number of the one I removed is 3916021. Any help would be appreciated.

I am not sure but I think I got it fixed.The old sensor was covered in a thick layer of some kind of lime buildup. Cleaned it all off and reinstalled and it seems to be working fine.Hope it's not just dum luck that'll break soon. Thank you for the replyand yes that is the correct part.
