I can't imagine 80+ deg water doing a real good job of cooling it? The way I see it, the water heats it up. While the water it hot, there is no need for it to be open. It opens once the water cools down again (ie, cold starts) Once the water is warm, ie, engine is up to operating temps, the devices closes until the engine is cold again. You said it yourself, its just ignition voltage and earth. How can this control anything? I have had an ABV (of the same design as above, in fact I'm pretty sure it was me that sent that pic to nark to put in the techdocs!) operating out of the car off a 12v power supply (I was checking to make sure that it worked, because I had previously had two that didn't work!). It opened/heated up fine (I think you would be surprised at how quickly the valve closes from a cold start...much quicker than your car heating up fully) without water lines attached Edit: I guess it might idle a little high on warm starts, but I don't think you would notice it much, why not try it without the water lines and decide if they need to be hooked up (save some work...)
