Just got caught in major rain, no power after I turned car off

Right, I completely understand. Basically right now I'm going to order a new link from Classic Industries (cheapest I've found at $24.99), hopefully find some help to push it back into the garage, then look for any causes while I wait on the new link to arrive. My oil pan gasket is leaking slightly, so I had already planned to pull the motor to address that this fall, I'll probably trace more of the wiring at that point. This is the first issue I've ever had with the wiring, it all looks pretty well done to me. The car was restored about 7 yrs ago.
