power supply for aerator pump?
 

I am using the Tsunami 800 pumps for my ballast system. Do I need to run a separate power cable from the battery to the dash switch or can i run the power form the dash power supply going to the rest of the gauges? I also will have a relay on the switch for safety. Only one pump will be running at any given time. The system will only have 2 pumps in it, one fill and one drain.

Thank you

They only draw 3-4 amps. You should be fine running off the power supply or fuse box thing. Its best if you have an empty spot and it's own fuse.
