So I recently bought a zonestar p802Qr2 as my second printer and iv put it together, but when I try to print one of the extruders always over heats. I have the temperature set to 203 but only one extruder will go to that and the other will pass it up until it says def where the temperature would normally be

Maybe the second thermistor is bad or plugged in the wrong place ( firmware config? ) .
Can you measure the resistance of both with a multimeter?

Black, red, green and blue cords seems to be the connection of a stepper motor. Some steppers come with extra wires ( not needed ).
The thermistors are usually white wires with a harder, stiffer high-temp isolation.
