3 wire Bilge pump or aerator pump?

[hikick1]

This pump is connected to an aerator switch. I have two manual rule pumps.. one high and one low. The high tule 500 turns on when I flip the manual aerator switch. The rule does not go to a through hull fitting but instead two hoses to the aerator spray heads. This white box is currently connected to the automatic livewell control and goes out an upper through hull fitting. This doesn't seem right to me. Is this correct? Are two hoses switched? The upper 500 rule has a y connector...I can post more photos

Draw a diagram that shows how they are connected then post it on the correct forum

I reposted in wirings. Thanks. I am familiar with the marlan diagram for the new pump with 3 wires. My pump has 4 wires.. I called marlan but they said they have changed ownership and don't have the information. 1993 Ebbtide Dynatrak 180 bass boat with 1994 johnson 150.
