The check engine dashlight bulb is just a normal wedge type bulb,its the same as the other wedge type bulbs used on the other warning lights and for dash illumination. The wires going to this check engine dashlight are the following,a Brown/white wire that comes from ECU wiring connector terminal F5,(located in the blue ECU connector).The opposite side of the check engine dashlight circuit goes to a Pink/black wire that goes to fuse number 10 for power.
