I can't tell from the pics (too small), but does the car have aftermarket angel eyes installed? If so, is there a switch/button inside the car that those are tied to? Perhaps on the steering wheel? Maybe the guy somehow used the horn relay for those?
Not sure why the windshield washer resovior would be missing. Only thing I can think of is the car might have been in a front-end accident and whoever put it back together went the cheap route. Just a guess.
46 & 2 just ahead of me...
