this thing is driving me nuts

found the wire, it's a black one

there is about 6.5 volt current on the wire
if a hold it against the chassis , the gauge maxes out
i measured the sensor, cold it gives me about 1010 mOhm
if i pour almost boiling water on it , it goes to 250

sounds good right

not so

i connect everything
when i turn on the contact, the needle slightly moves
to 50C
but it does that regardless of hot or cold engine
so it doesn't mean jack

i drive the car for a good 7 minutes,
it's a sunny day about 70F inside more in the sun

nothing on the gauge
i let it idle for a good 4 minutes
still nothing

sureley the oil temp should be more than 50C by now!?
if i measure the sensor, it does read low resistance`
