Cleaned it up with electrical cleaner and a needle, its like new now, Ill remember the vinegar method for next time, thank you, the corroded connection is now on the outside, with a male and female spade connector (bomb proof). Still doesn't work!!!!!!!!!! I'm now going all the way from the back to the front to make sure that everything is connected to the instrumental panel with a good connection. That'll be 17 wires and the jump connections inside the instrumental panel loom.
