pump

Hi All - I'm considering installing a Garmin or Simrad autopilot on my Seafarer. For those that have tackled this project before - where have you installed the pump and heading sensor? Any pictures would be appreciated. Thanks!

I have a 87 offshore pro 24 (248g). I’m looking for the wash down/ live well pump?? I can see the y valve on the back transom in the livewell but cannot find the pump. Also anyone can tell me how to fill the freshwater tank. I apologize up front for the dumb questions. thank you for any...
