wiring harness question

i have a 91 na. my question is about the round black plug that is bound to the harness in the same area as the water thermo sensor plug. i dont know what it plugs into. the water thermo sensor plug is green and rectangular, and right beside it is a round black plug about the same size. i am guessing that it may be for a t 2 or something, and is not used on my na. any ideas guys?

Yes, it's for TII's and automatic NA's. It's the plug for the water thermoswitch that turns on a small electric fan.
