A bloke I know, I won't embarrass him by naming him (Kyle) was looking into a variation on this theme a couple of years ago and promised me a write up on it. His method was surprisingly simple. Apparently you can buy small adhesive heating pads that are designed to heat the handgrips for motorbikes. He got a couple of those to use.
The actual reflective/glass bit can be removed from the housing quite easily if you know the right direction to yank it (and no, I don't know). So he pulled the glass and stuck the pads on the back. My recollection is faint, as there was a lot of drinking over the rest of that particular weekend, but I think some of the wiring was either already there, or there was room in the plug for him to run his own wires to that point.
The European manual I looked at last night had the full wiring schematic in there so after that it would be pretty easy I would have thought. I assume it is triggered by the rear demister switch or something similar.
Not sure on the original question of whether Triton mirrors are the same as Challenger mirrors, but I have at least one idea of how to find out. If you go to the partsouq website (make sure you use the "new" database, there should be a link if you're in the old bit) you can enter your VIN and get into parts diagrams with all of the relevant part numbers for your model. So in this case you need the VIN of a challenger with the right mirrors and then the VIN of a Euro Triton that you think would have heated mirrors and then you look to see if the part numbers are the same or not.
As for finding the VINs, you can often find them on sites where cars are for sale. Alternatively, you can use a body code number to get into what you need. If you look at the start of any of the workshop manuals they describe how the body codes are formulated and you can usually work out what the code should be for a particular make and place if you follow that guide and reverse the concept.
