Where/How does Temp Wire Exit Harness, ..to go under engine to the switch ? Options

[Literati914]

I've got a '72 so have no temp sender originally and am adding one and a gauge. My question = where's the best place for the single (GR/BK) wire to exit the loom from the tunnel (Im trying to mock up changes to my '72 harness). I'm concerned about burning up the wire if it gets too close to exhaust. What about having it exit with the Yellow wire from the relay box to the starter then having it continue and loop under the engine? .. or possibly have it exit under the bottom of the snorkle fitting, and just reach straight across the the temp sender? Thoughts?
