Thanks for the feedback. I found a Dodge washer reservoir that fit well on the firewall and almost looks stock. I was bashful about drilling new holes in the hood of my truck, so I got first-gen Firebird/Camaro spray nozzles to spray out from under the back of the hood, so they're hidden. The momentary push button switch was tricky to find. Could either use a horn button or a starter button, either of which can handle the current. Or maybe an AC switch, considering how short the button is pressed. I don't think it would fry.
