Good news all....I dried the circuit board and enclosure, gently cleaned the corrosion on the board with a toothbrush, reconnected everything....and just like magic, she started right up!!! Problem solved. I do plan on finding the source of the leak and getting the waterproof case. I am relieved that I didn't have to drop another stack of cash to figure this out. The ONLY problem so far is that my airbag light is on and my interior dome light stopped working...smh. Go figure. I'll work on that part tomorrow
