how do i tell which thermos are from which falcon or are they all the same. the only reason i ask is that people are saying that ef thermo's are easy to use the el's. so the question is how do i tell the difference.

Cheers

Theyll all be the same

All 3 models are different.

EF have 2 plugs, as the fans are capable of 3 different speeds.

EL physically look the same as an EF, but only have 1 plug, and only offer 2 different speeds.

AU only have 1 plug, but the fans are sligtly offset, with the passenger fan being lower than the drivers side fan.

They all work the same in the end, but they are all physically and electrically different.
