I fitted one to my CBF and think it's called the diagnostic socket (DS)??
I think you've made a good choice of GPI, being plug in without cutting any wires.
I don't know where it is on the CR but to give a clue, on the CBF it wasn't just an empty socket, it had a dummy plugged in, so looked like an 'in use' connector.
this is the GPI-DS connected on my CBF (tank was raised to see this).
I think the dummy connector is the empty red bit behind.
