OK you sparkies,
I am replacing the forward bilge pump in my 86 300DB. This area is just forward of the battery compartment. The shower also drains into this area.
The old pump has three wires: Black, Brown and Brown/White.
The new pump only has two wires, brown and black. The brown wire goes hot (+12VDC) when a switch is thrown in the bathroom.
Have no idea what the brown/white wire is for, unless it is hooked up to one of the engine bay pumps and when they activate it activates this one. This could cause this pump to run dry which could burn it up right? What is the third wire?
