I have a 07 ZX225, I just up graded my livewell aerators, but want to also add an extra bilge. I only have one and it is manually only. There are two sets of black and blue wires coming from the same place as the aerator wires, they have a small tag that says livewell but aren't connected to anything. Don't know what they are for. I traced the bilge wire for a short distance but didn't see a second set of wires an extra bilge. I have buttons for two bilges and would like to hook a second one up that is also an automatic.
