We have a hydraulic shop here in MI that i was at a few years ago and this dodge ram was in the shop and when i was looking at the install i noticed these wires connected some kind of sensor that was on the tank, so i had to ask what the heck it was since ive been in to hydraulics for 13yrs and never saw this before. To make a short story even shorter come to find out they where block heaters for engines! i don't know if they only plugged them in at night when they charged the batteries or may be a ac/dc converter and they would be on all the time. The installer said he also had them on his ride and id made a huge difference even though it would only warm up the oil in the tank ant not the lines/hoses but with the warmer oil the pump wasnt trying to pump thick cold oil. hope this helps you or gives you a idea for something.
