i have a california 88 mas air car that I purchased a 80mm mas air meter for, the plugs are different, the one on the car is rectangular and the plug on the meter is oval (like the later cars). the wire colurs on the retangular plug are red,black,blu/white and ltblu/tn. I orderd a plug with no wires just a plug and pins off the internet. I am unsure of the order of the wires, looked at the wiring diagrams, still unsure does any one know what order these wires go??
