Heatbed 3 pins connector


I killed my 3 pins connector. When I tried to solder it again, it looks like if there is a strap between pins 1 and 2 on the heatbed (solder looks like a square over both). I have not checked that before solder it. Could someone check it (power off the printer and check continuity with a multimeter between this two pins) ? Or do someone have the pinout ?

Thank you
