Underwater LED install

[mattsask]

So the wife got me the "loki" boat plug light that replaces the rear drain plug flange. The install looks easy enough, but does anyone have a suggestion about the wiring part of it? I thought I saw a post about the wiring already being installed and run to the transom in the newer boats. Can anyone fill me in on where to find the wire that I need to tap into? Thanks!

There’s a pig tail to the top and right of the transom, looking inside the engine bay, almost tucked behind the black trim piece that runs across the lip of the top deck of the hull. Just follow the hanging extraction hoses up from the exhaust pip and you will see it.

You're the man, stazi! I have a couple other underwater LED lights that are on the weaker side. I might install them to run with the plug light. Can I tie those in with the boat plug light on the same wiring harness?

Probably. All depends on how many amps your lights are pulling. Do you have the specs on them?

I do, but I'll have to dig them out and get back to you.

Matt, I have 2 sets of lights running off one switch. You may want to consider installing a fuseable link in line to the switch, otherwise you are relying on your switch breaker should anything bad happen.

Wait..... so there are already wires ran for this???

Could be. In the past 7-10 years, we've seen more and more manufacturers move to a common wiring harness for all their builds. The harness is built with all the leads needed to service all or nearly all the options the manufacturer offers.

Gone are the days of a base level harness and the assembly tech custom wiring portions of the boat for the added options. Its plug-n-play as the boat goes down the line. The extra materials used for the harness is offset in saved labor time.

[Stazi]

Yes, the wires are there on the latest Moomba models. And they are connected to one of the accessory switches on the dash

Bought a new Loki-2 light and it won’t fit between the wakeplate hinge and the hull so I chamfered the bottom edge to allow it to fit.

how is the light any pics?

[mattsask]

What the heck. Their whole sales pitch was that it works without interfering with the wakeplate. Mine is still in the box. I had my work cut out for me fishing out the fogging straw that I shot into one of my cylinders when I winterized in the fall. That's 7 hours of my life I'll never get back....

Maybe on all the other boats, but the fact is our drain plug is way to close to the wake plate. I modified it in 5 minutes on my mini belt sander. I had to take breaks and cool it off a few times as the bitch gets hot grinding it and I didn’t want to screw up the LEDs by getting them too hot. The manufacturer even says do t leave them op out of the water if they will burn out. I tested them for 30 seconds a coupe of times as I was wiring them up and it was fine. There a bunch of wires that need solder g so o wanted to be sure it was all good before I glued the bitch in!

so i contacted customer service and sent them a pic of the drain plug per there request... they said the mormo should fit without modification. i ordered one. i will update after i install it.

That looks way thinner, but it’s nearly 3x the price. It better be bright as hell for that!weird shape they. Looks like Dame Edna’s glasses.

I used E6000. But any kind of waterproof silicone would be fine.

Matt,

blue i illumination. Turn the UW light switch on and put a volt meter in the leads and see which blue shows 12V, then turn light switch off to confirm.

My switch was the closest accessory switch to the steering wheel

For these lights that fit the drain plug hole....I see that a drain plug functionality is still there but do you lose the ability to snake the oil drain hose out the back for oil changes?

I would imagine you could still get the hose through that hole

So you are saying all that illumination in the video is coming from the one plug light?

Mine was super underwhelming, and I went into it with low expectations.

So i just wired in my mormo light to the two pig tails from the factory. They are powered by the same switch as stazi said: closest to steering wheel on left. Flipped the switch worked for 3 sec and blew breaker under steering wheel. Reset... same thing. What do i do now...?

Update:

I was looking at boat plugs spec on the titan and mormo and it says they require 8 amp min. I looked on breaker for underwater lights and it says 3 amp... obviously that’s the problem. Well right above the underwater light breaker is the breaker for docking lights which is a 10 amp breaker. My boat doesn’t have docking lights so I swapped them and now it works fine!

Anyone have any input against doing this...?

[MLA]

I would not assume that a circuit protected by a 3A fuse has a wire gauge that will exceed that new 10A breaker. Simply swapping breakers, may not the proper step.

X2. Heck of a light you have. You don't want to cook those wires.

[c04rsx-sm]

Are you saying the gauge wire should be bigger?

[zabooda]

Are you saying the gauge wire should be bigger?

Maybe. You need to find the wire size used and then a good guess on the length of run (I'm guessing 20 feet). The charts I see are all over the board on the wire sizes but for 10 amps should be 14-16 AWG for a 20 foot run. If you are lucky, they didn't install 18 AWG. You also have to look at any connecting parts to ensure they can take the higher current.

I dont know what gauge it is, but it needs to be a gauge that can support a 10A breaker. You upped the circuit protection amperage by 3 times. If the factory wiring was designed for that 3A circuit, you could have an issue with a 10A breaker. Now the wire is the weak link, rendering the breaker useless.

[c04rsx-sm]

thanks. I now see what you guys are saying... maybe i should just run my own wires with their own fuse...

Eusst1. You have same boat and light. What did you do?

[jph3]

Any updates on these installs by chance? I was going to order the Loki, but sounds like it might not be worth the hassle... especially if the wiring isnt rated.

It was not very difficult to run my own wire to a switch at the dash for my 4 Diablo lights. If you do rgb, it will have a controller box that you wire to, then just use a ground at the transom and power to the dash, which is fuse protected. Good Luck!!

[Steviemh]

I know this has been covered somewhere, but those wires that are pre-ran, are they the black and yellow wires that are plugged into one another? That’s the only wires I see back there with pig tails. Didn’t want to unplug them and hook up my drain plug lights with out checking first. 2018 Mojo

Marine illumination blue. May have a black tracer, but the primary color is usually blue.

[spatty99]

The wires are in the engine bay, against the stern wall on the starboard side (not by all of the junction boxes on the port side).
Take off the black plastic decorative "Moomba" thing for more clearance. You can also remove the starboard side engine/ballast divider panels, although it isn't necessary.
The wires are almost impossible to see without first pushing the bilge vent hose(s) out of the way. Even then, they are zip tied to a horizontal cable run (terminated ends stick out on the starboard side of the wire run), so you can just barely see the wire ends poking out. They are labeled as underwater lights (there are two pairs, btw), so you'll know you have the right ones (and are blue with grey stripe, if I remember correctly). Clipping the wire tie provides enough slack for connections.

[jnr4817]

Old thread I know but buying some stuff for winter projects. @spatty99 you mentioned 2 pairs. What is the other pair of wires for if not underwater lights or do they belong to a different acc switch?
