2000 190 Sea Ray BR
Engines
5.0
We changed boats to a new version and I want to add a GPS Depth finder and Interior Lights.

On our Oval Electronic Switch Pad, I am pretty sure I don't have water system and I know I don't have wipers. I found wiper wires so if I had to hook up one of those new items to that it is fine. But not exactly what I want.

This boat has EIM and it is sealed and unlike my older Sea Ray fuse panel isn't exposed to add connectors to it.

I want to do this correctly and so I am wondering if anyone is willing to guide me through this adventure.

I would like a detailed diagram as all my wires are marked with 3 digit numbers and I am not sure if that helps. I need to know where I could either connect to constant power directly under the dash for GPS finder. Also, I would like to have my interior lights work off the water system button as I am pretty sure I don't have that on my 190.

I really appreciate the assistance with this and guidance.

My 2003 Select 200 Operators manual has a full 2 page fold-out schematic in back. The oval switch pad is a an unreliable electronic remote for the switch box with the thick wires in back. I imagine you could grab the high amp wiper output leads there. Easy enough to drill holes in your dash and install marine toggle switches.
 
Andrew,
Feel free to ignore the above comment. You do not need to drill holes in your dashboard and add non Sea Ray components. The unused switches on the switchpad can be re-purposed.

The switch pad is actually part of a two part system. The other part is called an Electronic Interface Module (EIM). The EIM is part relay, part circuit breaker, part switch. The switchpad communicates with the EIM by internal network telling it what mechanical switches to activate. The EIM has a large multi wire plug. The wires on this plug are all positive lines that go back to the devices controlled by the EIM.

Sea Ray utilized the same switchpad and EIM configurations across different models, so that’s how you come to have a switch pad with a wiper switch, and no wipers. So while the EIM is a common part, and the plug would be the same for all boats, your boat may not have a wire in the plug that would match up with the location for the wipers. In that case you might need to insert a pin connection. That’s why a good place to start is with any switchpad marked ACC. These are accessory switches and correspond to a wire in the EIM plug. If it is unused then there will be a stub with two to three feet of wire in the harness.

So the best thing to do is look at the owners manual. It will have a comprehensive wiring diagram that will show the PIN numbers on the EIM plug, as well as the color codes of the wires. On our 02 280 the wires were not only color coded but also printed with the wire’s purpose every foot or so. Pink wires for example were marked “fuel” and made up the power side of the fuel gauge circuit.
 
All of my wires have a 3 digit number printed on them, so I will have to make notes as I figure them out.

I found this online is the manual everyone is talking about? Page 18?

I know I can have lights on the "wipers" button, but I am looking to direct wire GPS/Finder to power and from what I can tell there is no direct access for that like older boats.

Just looking for some insight.
 
Look at the middle of page 18. There is an accessory (ACC) circuit that goes to pin one. If that is unused all you need is to find the wire stub at pin one and attach that to the positive of your chart plotter and ground the plotter and you are good to go. Just make sure the fuse for that circuit is sufficient/proper size for the plotter.
 
Given the apparent level of expertise, I forsee problems if he tries to utilize the switchpad. His work may confuse future mechanics and operators. There are numerous posts by owners who have given up and replaced malfunctioning pads with aftermarket conventional switch panels. KISS, Good luck to someone who wants his hand held.

He has a functioning EIM system. He does not have a water system, or wipers because his boat does not have those features. Why suggest a helm conversion that would cost thousands of dollars when all he has to do is find the wire and attach a solderless connector and a bit of wire to his new devices?

This.

Andrew, think of it this way. The EIM system (control panel/fuse box) is akin to a fancy toggle switch. The two pieces talk mumbo jumbo to each other, but on the boat side of the system, everything is exactly the same as a regular switch/fuse setup like you're used to. It's just all "new age" in between. But the good thing is you don't have to worry about that in between stuff - just do as Henry said and look for the boat-side of the wiring and connect there. The rest will take care of itself.

I didn't open that link, but you might find your owner's manual on SR's site. Look for the "supplement". However, if yours isn't there, look for a different year and/or model as the wiring is standard.

FYI... I'm pretty sure your switchpad already has the cockpit light "button"... it's just not hooked up. It's the one that kinda looks like a light bulb.
 
I would repurpose the EIM system as suggested. The critical aspect would be permanent labeling of the switches.

On the other hand, there were places for additions on my dash. There are two layers of fiberglass with space between them for the factory gauges and switches. There would also be room for some of your own. Here I put in an impeller pressure gauge and halon status monitor alongside the EIM console.
