Well we ended up with a Thuraya phone with only a$15 month plan which should work out fine as we will only use the phone if we need to.

Hi our truck has a wire going there too , what it is for i do not know.
But the speedo should still work because its cable driven.
You might need to take the peice off the gearbox and see if it drives the cable.
