I think I see it. I actually ran the black wire to one side of the lamp and then I grounded the other side of the lamp in series with the other lamps/gauges? So if I am getting this right, the way it is wired now, that light will not even light up? Now the gray oil lamp wire, will now go to the oil pressure gauge sender terminal, with the blue/w white trace feeding it power and also have the ground on the ground terminal? I am going to post a few pictures of this mess shortly, so keep an eye out. I can see why printed circuits are so much neater.
