(DG) EV1 sensor Location

I just got my new EV150 autopilot and I am planning where I should put the EV1 Sensor. The boat is a 1999 Sea Ray 370 Express Cruiser.

Any idea where the EV1 should go? The old Autopilot compass was below deck under the steps. Should I put it there?

Please let me know what your thoughts are and or if you know where people are mounting them.
Thanks in Advance
