I recently purchased a complete harness and computer off of a 88 cali car. Everything looks good except the mass air plug. It is square instead of oval like on 89 and newer stangs. It does have the 4 wires coming out of the plug and they are the same color as my dads 93, but will not plug into the meter I have. Is there a different meter for the 88 CA cars??? Also anyone have pics of there meter plug off of an 88 mass air car???
