Pattern for motor plate. I used aluminum when I could get scrap for for free, steel now.
Black and white wires go to motor(piece of extension cord), black and red from solor panel. I use a piece of rock to keep timer off bottom. I drill a few 1/8 holes in bottom to let any rain water out. I learned that the hard way. I ruined a timer leaving it on bottom with no holes in box. I learned the hard way to make small holes in ammo box. I met a nice group of red friends when I opened a box once.
