Default Bilge pump

Ok, this shouldn’t be so hard, but I got frustrated this weekend and had to walk away. But, I am splashing next week so I need to get this fixed. I need to replace my forward bilge pump and float switch.

I have factory black, brown, and brown with red stripe coming to the bilge.
The bilge pump has brown and black wires.
The float switch has brown and black wires.

I have a lighted switch at the helm.

Suggestions on how I wire this together! I am going back to the boat 4100 SCA) on Wednesday.

First verify brown with red stripe get power only when the helm switch is on. If this is correct wire it as follows.

Brown wire coming to the bilge from the harness gets wired to brown on float. Black of float gets wired to brown with red stripe and brown of the pump. Black of the pump to black of boats harness.
