A65 & EV100 Power Installation ???

Hi, I have an A65 GPS/FF combo, old but love it! On the way is EV100 Autopilot w power hyd pump...going on 23' V8 power boat (ocean going).

1. Do I need to?
2. Should I ?
3. Can I ?

Connect the Autopilot to the A65 ???

Why or why not to connect it ? And how to do it?

Also, the only Port open on the back of the A65 is the "AUX" port....the others have the Power, GPS, Sonar and nmea/VHF attached to them.

thx in advance
Justin
