i am making my own ic sprayer from parts around the house, and i have a 12v pump but i don't know where to get a power lead from. i am going to mount it in the cabin, so i can't use anything from the engine bay. i was wondering if anybody could guide me to a good location.
and i would like some ideas on mounting a water tank, i was thinking water bottle sort of thing where i can fill with cold water and ice and use that inside the car, but then i was thinking tank in the trunk. anybody do something like this before?
