My check engine light and the oil light is on. oil light flickers on and off and stays off then when im stop it flickers back on and off again. The ecu light blinks once every 3-4 secs. The car is a 1990 hatchback civic si with a jdm b16a 2nd gen swap.
wire harness is stock. the ecu is a chipped b16 ecu. Could bare wires cause the oil light to flicker on and off? Besides the ck engine light and oil light the car runs great. The are also some pulled wires from the ecu.

 

one blink is for the o2 sensor. and your oil pressure plug is right above the oil filter the plug probably isnt all the way on.

 

Thank you so much <3 really thank you! <3 <3
