Wire harness sander/ pump setup

I am trying to figure a way to run a electric pump continuously when the vehicle is running to keep solution in suspention. The pump will stop running when key switch is shut off. I would also have a marine battery to help as well.
Because it will have a big draw my thoughts were that we might be able to accomplish this with the big wire harnesses and controler you use with electric sander setups.
Do you have any thoughts on how I might be able to get this to work. Tank would be inside one of my vans.

You need a wiring set up similar to a boat bilge pump. No need to have major current draw, as long as the pump is not too big.

Just connect it with the orange wire under the dash. Ask any mechanic; orange is switched, yellow wire is hot even if the ignition is off. Or--maybe it is the other way around.

Power inverter Deep cycle batteries all hooked up to your current battery. You can get an inverter as big as you need. Also Sine Wave is ideal vs. Modified Sine Wave but if youre just running a pump it's whatever. How big is this pump?
It is very important for you to post your results once the problem is solved so that people will be able to reference a solution to their problem down the road. YEARS may go by and someone has the same problem PLEASE POST YOUR "IT WAS FIXED WITH x SOLUTION.
