[Tom french]

I have an old attwood guaradian 500 bilge pump which seems to have given up, maybe due to age. does anyone know if the wiring for this is the same as the newer version Sahara s500 As id like to do do a quick change over.

Every bilge pump I've seen just has 2 wires into it, esp a common brand like Attwood.

Hi, this one has three, but I think one is for the auto or main part of the switch.

They typically have three wires; one for auto power, one for manual power, and ground.

Yeah, so in an auto pump one wire is neg, one is switched 12v and one is direct wired 12v.
