IIRC, that is the wiper delay module. Not necessarily hidden to keep one from finding it, but just installed that way for cost cutting. My wiper delay failed and that part (circuit board) was a dealer only item (somewhere near $100 or more) so I bought a matching resistor like the burnt one ($2 at radio shack), and soldered it in. What a rush to save that much money on a repair. I have been reading your build from the beginning, and i finally got a chance to add .02 cents. Keep up the awesome work sparkydog! (OK. now .04 cents)
