oil pressure switch on head what colour

can anyone please tell me what colour the oil pressure switch is supposed to be on a 1989 kjet 8v, i put a black one on but oil light is constantly flashing

No matter, guess you put the switch in the wrong place. Where did you replace it?

PROBLEM SOLVED CHEERS PEOPLE THE TOP SWITCH WAS A 1.8BAR AND NOT A 0.3 BAR KNOWN AS A BROWN SWITCH
