Acc1 Switch

On my 330, dash switch ACC1 was unused and ACC2 was wired to the underwater lights. When I wired ACC1, I found that it was wired to a red/violet #14 wire designated #500 (under the dash). Just inches out of the electrical interface module under the dash(the box with the push breakers) this wire splices to a brown #14 wire designated #349 that ran to an unused plug next to the starboard engine.




Sorry to bring back an old post, Trying to get my underwater lights wired to ACC1 switch. I was able to locate the plug and wires listed above. Brown # 349 and black #348.

I tried hooking up the red from the underwater lights to brown and black to black... and then hit the switch and nothing.. Am I missing something.. I thought this line and switch already had power. Do I have to turn something else on or do something different

Have you considered just swapping the switches/wires on the existing switches?

I might try that.. I should add that ACC2 is wired to the factory white underwater lights and I added Lumitec seablaze X in blue and wanted to add them to ACC1.. even though I don't really use the white ones.. I could track down their wires

So I did the same thing. Turns out the wire in my schematics that was supposed to be operated by accy1 was actually powered by the water pump button, the one everyone asks about that is a rectangular box with a squiggly line going through it.Not sure why. Just a SeaRay thing I guess. I still have not found what the acc1 switch powers. Check the wire coming from the ECM, I believe you stated it was #500, and make sure you actually have power on that wire with the acc1 switch. If not, try the other switches to see if any of them power it. If you actually go in to the ECM, you find what I did - that the labels on the outside do not actually match up to the pins on the inside. Guess just another SeaRay thing.

Also - that acc1 switch should be going through one of the breakers on the ECM.
