What is this? Electrical

Getting ready to make a wiring schematic for my boat as i tear it down and I see this behind the tach. What is this?

Stratos 290 S/f

Not that familiar with it, but with 3 spade terminals attached to it, it appears to be a multi-function circuit board. Is that black square object a peizo alarm? If so, it may be an alarm for low oil pressure, high temp, and low battery voltage...but I'm just taking a shot in the dark.

Someone more familiar have more to offer?

There is actually six spade connectors 3 on each side. The alarm for oil pressure is actually located somewhere else.

I think you are about to answer your own question! Finish your wiring schematic, and THEN try to figure out what it is. I'm guessing the answer is going to be alot more clear once you know what it is connected to.

If I were a betting man though, I'd say livewell timer. Clean off the top of the IC and post the numbers. Again, if I bet, I'd say there is probably a '556' somewhere on the top of that chip. It looks A LOT like a LM556 timer circuit with a relay to turn on/off a pump.

(the square box is a relay, the little guy to the right is a transistor to drive the relay, a couple resistors, a couple capacitors, and what looks like a standard lm566. yep, timer)

Looks like someone stayed at a Holiday Inn Express last night! (j/k)

You, sir...are awesome!
