Interesting thanks for that tip. however, if I do that won't I be left with a
thermocouple wire permanently dangling from the engine? Understood this is the
best option but is there a second best option that doesn't involve permanently
afixing the wire to my engine?

Thanks I knew I was doing something wrong but once explained it makes sense.
