Clois - I would be skeptical to say the least that you received 3 bad boxes. It is more likely that the problem is either something else or a wiring problem that causes this failure in the boxes. I mounted mine on top of the passenger footbox in the engine compartment and have had no problems and I would doubt that many get hotter than mine. Two things stand out - first, you had allot of new electrical stuff, second - you mentioned everything is wired up/connected the same way. I don't want to offend you but could it be wrong. I would think you have already scrutenized this but you never know.
