I dropped in a ls integra engine into my 93 civic. the problem i am having is my stock speedo plug was all dirty and was causing me to through a check engine light and my speedometer not to work. So i found a nice almost new clean plug with wires. Well my stock wiring harness has three wires: one Black,a black with yellow stripe, and a straight up orange one. Well the new plug im about to put in has: yellow with a white stripe,yellow with green stripe and a black one. Can anyone help me out on telling me what one goes where. Or another idea on how to fix this. Thanks alot, and please through something at me if you know.
