That sir, is some messy wiring. Kudos though, it looks great otherwise. Besides who cares about what's behin your great looking front panel. I like that you are operating the pump separately, but just be aware that you may want to insulate your rims with something to avoid the heat loss inherent in constant recirc. It won't matter as much in terms of your mash, but it'll certainly make your SSR turn on/off more often and they do eventually burn out.
I will keep the insulating in mind, ya messy huh, good thing I dont do it for a living or I wouldnt be living.
The transfer tubes are long too, oh well will test this weekend and see what happens.
