my cluster now decides it doesnt want to work either gauge, the cel, and the oil pressure light i know that cause i ran it with a sensor undone and the oil pressure wire OFF and the light still stayed off...is it bad

 

the oil pressure light will turn on when the oil pressure sensor provides a ground. unplugging the sensor won't accomplish anything. you need to ground that wire and then see if the light comes on. is it possible you have a loose connection or wire in the back of the cluster plug?
