    Howdy, How big of a deal is it if the wires coming out of my EEC pin connector are the wrong colors? For instance, pin 46 is supposed to be black/white but mine is white/orange. There are a bunch of others that are wrong too (perhaps all?). I have the '90 electrical/vacuum shop manual, which...
