I have a 1990 buick skylark.2.5 liter eng. Auto, A/C. I got a new plug from the buick dealer.A buddy installed it not thinking about it he got the wires crossed. All 3 wires on the new plug were gray. Not knowing that the fuel relay, fuel injector, an all that is included in that circuit. So now I have no power to the injector. I need to find out which of the 3 wires go to which of the 3 prongs on the oil sending unit plug. So THANKS FOR ANY HELP. Tommy

I don't think the injector circuit is involved here-see pic below

Thanks for getting back to me so fast. But I also need to know what color wire of the 3 goes to which prong on the plug for the sending unit. THANKS AGAIN. Tommy
