Coolant temp wire

Can anyone tell me or have a picture of exactly which wire in the harness goes to the coolant temp senser under the filter? It's an 83 harness with a 79 12A. I'd like to find out as running the car without some sort of temo guage kinda makes me nervous

if you follow the main loom from driverside of firewall down to the chassis rail
theres a big black connector, its almost under the brake master......but near the rail!!
if you have a diagram its the X-01 connector, but the diagrams suck, so wouldnt bother!!!!
it has 2 rows of pins:
X X X - Y X X X X - X X X
X X X - X X X X X - X X X
on this connector the yellow wire with white stripe is the sensor you are after!!!!
its in the position of the Y above

Yeah I think I may have found it but I have to move the harness to the other side of the filler neck to get it closer cause the wire is too short right now to get to the sensor
