To be honest I can't recall if it was at the rear subframe or to the front left part of the bike somewhere ... I know on the GXSR750 it was the left side of the rear subframe .. and I know on my F4i it's same location as yours... because to fit my race plastics I had to make a bracket that would allow the tilt swith to mount to the inside of the race fairing since I took the headlight and upper fairing off... Just a simple Lshaped bracket is all that was necessary...
as for why you can't remove them.. the electronics is set up for a certain resistance reading given by the tilt switch.. as soon as you break that out of the circuit it no longer gives that reading to the ECU and it shuts off the motor thinking the bike is on it's side and nolonger at a safe angle....
since you have been the only owner of the bike... the possibility of someone messing with it is out.. so it must be faulty.. if in deed that is the cause to your bike motor shutting down... with a freinds help.. start your bike.. let it run and lean the bike over from side to side and see how far down you can take the bike before it shuts off.. if it shuts down before the amount of angle that it should then i would look to replacing that switch or look to see if something came loose... In your manual it should state at what angle your tilt switch shuts the motor down... it should also state what resistance your switch should have... you can also check that with a meter if you got one... just be sure to have it set for ohms and not volts
(x amount of resistance will keep the motor running... no amount of resistance will shut motor down... this is why you can't remove it.. you remove the switch and there is no longer any resistance there... )
one way to determin possibly if it's a mercury relay or a mechanical relay is.. all mercury relays I've seen here at work are enclosed and you can't open them... (obviously cuz mercury is hazardous) if your relay is a box shape with screws holding a cover on it.. it's gotta be a mechanical relay.. and if that's the case then you can open it up and you will see a weighted ring that slides from side to side along a "pole/rod" at either end of that the brass rod is no longer bare and is most likely covered with something... once this ring crosses over that your resistance reading becomes nothing .. this is how the switch detects what angle you are from left to right.. so this means if you permanently keep the ring centered you will always have a constant resistance to keep the motor running.. this is most often done by filling the cavity with silicone... let it set till firm then replace cover and install with arrow UP (lol) and you're all set... AND YOU ARE CORRECT this removes a safety factor that could potentially be dangerous if one goes down and the motor is still running and in gear...
If it's too good to be true... then you must be Dreaming.
