Marshfly Posted September 9, 2016 Report Share Posted September 9, 2016 I figured all of the other Acc switch positions but Acc 2 seems to be eluding me. It's hooked up to a Blue and purple wire. Acc 1 is the live well recirc and Acc 3 is the Livewell light. Any clues? I was hoping to use it to switch a wash down pump. Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted September 9, 2016 Report Share Posted September 9, 2016 If you boat is like mine, there are several accessory switches that are not connected to anything. They have wires coming from the switch that go into the wiring chase under the deck, then terminate somewhere in the bilge. They usually have a Doutch connector just hanging there or in the middle of the wiring harness. Kind of hard to find some of them. I even have two attached to the underside of the rear deck. Had to use a mirror and light to find them. They are installed at the factory so you can add stuff like a wash-down pump. Maybe someone knows that the blue and purple wires go to if they are dedicated colors for a particular appliance, but they could just be spares for aftermarket additions.

Marshfly Posted September 9, 2016 Author Report Share Posted September 9, 2016 That would be awesome. I was dreading having to feed wiring through the chase. Do you have the grounds run back to there as well? Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted September 9, 2016 Report Share Posted September 9, 2016 Yes. There are probably 5 pairs of wires attached to my accessory switches (hot and ground wire) that are unused, just there for adding stuff. I have two in the console and at least three in the bilge. You have to find them, then turn the switch on and probe them for voltage to determine if you found the right wires. There is probably more than one unused pair in your bilge.

JnamJnam Posted September 12, 2016 Report Share Posted September 12, 2016 I bought my 18HPX with a wash down pump. It is wired to one of the accessory switches on my console. Link to comment Share on other sites More sharing options...

I have to wire in a relay anyway as that switch only has a 5amp breaker and the pump needs 15 amps. JnamJnam, do you happen to have a picture of how your pump is mounted in the bilge and where the outlet is? I'm thinking about putting one of these on the deck right in front of the engine. https://www.amazon.com/gp/product/B000O8D244/ref=ox_sc_sfl_title_3?ie=UTF8&psc=1&smid=ATVPDKIKX0DER Link to comment Share on other sites More sharing options...
JnamJnam Posted September 12, 2016 Report Share Posted September 12, 2016 I attached a photo of where the pump is. Its the only picture I have on my phone that shows where it is. I will take more detailed photos when I get home. I do recommend adding a ball valve shut off switch (which I still need to do) because when I am running on plane water is being picked up and forced through the pump as you can see in the picture.

Marshfly Posted September 12, 2016 Author Report Share Posted September 12, 2016 That's exactly where I was going to put it. I keep the valve prior to the livewell pump closed anyway because I seem to get more water in the livewell while running than the overflow can evacuate and it fills up and spills onto the deck.

conocean Posted September 12, 2016 Report Share Posted September 12, 2016 Marsh- I experienced the same thing. If my valve is open 1/2 of the way then the drain tube will handle the water just fine while running and I've never lost bait that way. Also, for the sake of not drilling holes on the deck or running more wires.....if your livewell is plumbed with a recirc pump then you can buy a hose that will fit the recirc fitting inside the livewell which serves its purpose as a decent washdown pump.

I would love to see where the actual pump is mounted if you get a chance. Link to comment Share on other sites More sharing options...
JnamJnam Posted September 14, 2016 Report Share Posted September 14, 2016 Attached two photos I took this morning before leaving for work while still half asleep. Hopefully that shows enough detail for what you are looking for. Link to comment Share on other sites More sharing options...
Marshfly Posted September 14, 2016 Author Report Share Posted September 14, 2016 That is the only realistic place I could figure out as well. Thanks a ton for the photos. Link to comment Share on other sites More sharing options...
