As Ken pointed out those Scotch Lock quick connectors are less than ideal.   All trailer light kits come with those and are at best temporary.   I bought some wire connectors recently and wish I had them years ago.  They look like normal crimp wire connectors but have heat shrink already installed.   Insert the wire ends, crimp the connector and hit it with the heat gun and you are done.  Saves a lot of time and seems to be a water tight connector.   They come in a variety of sizes.   Reviews were 100% positive and many shops have adopted using this type connector.   I formerly soldered all connections and either shrunk wrapped or taped the finished connection.   I like these better.

What is the boat safe box. I see nothing having to do with speed control on this boat. I looked on google and didn’t find much on this box. What could it be there for?

Can someone post a pic of what the buzzer should look like. I have a new nautiques dash plaque and want to go back to one light and original buzzer. I plan to get back to original wiring but would like to see original setup.

My original thought was that the aftermarket light was for something else, but it looks to connect to the same wires.

I figure if you follow the wires from the Boatsafe box you'll probably find about 5 more Scotch Lock connectors and be able to figure out what original wires the thing hooks to.

Maybe somebody put the box there to deal with ignition noise etc just as a guess

Boat safe seems to tie into a lot! Blower and ign breakers. Blower, fuel gauge, tach, and more. What does it do and should it be removed?

Pics from above:

Thanks for the pics.   ...Today I learn that you are supposed to be able take that whole pod out on a 92.... Mine has 7-12 prior owner wires running through that don't have connectors (PP, radio, other mystery stuff...) need to figure out what each is and how I can make the pod fully removable...then rewire it to get rid of the daisy chain.

Thanks.

Starting this wiring project:

Plan is to get rid of much of the daisy chain: 
  • Running an additional 10awg pos and neg from block to dash.  
  • Removing all Red (pos) daisy chain (they are on the switch breakers, ign, horn, etc).  Using a bus bar for this.  Also using 10awg from Ign breaker to bus bar (I will continue to run through original breakers/switches from the bus bar).  
  • EDIT: Purple (pos (keyed power)) wires to gauges are run from the Key switch so it would need another bus bar I think.  I'm leaning towards leaving the Purple in a daisy chain.  Thoughts?
  • Planning to leave the Blue (pos) daisy for the gauge lights which runs from the Nav Light breaker.
  • Removing the Black (ground) daisy from the gauges and install a bus bar.  
  • I plan to leave the Black (ground) daisy to all dash lights (gauge and indicator)
I removed the Boat Safe box and associated white scotch locks.  The affected cables were 5.  Two were shortened to get rid of the open cut.  And 3 spliced with a heat shrink butt splice connector.

The blue scotch locks are for the depth finder.  Leaving as is.  

Questions:
  • Is my plan good (it is already started but could be tweaked)?
  • Anyone identify that orange wire scotch locked onto the blue (pos) wire in the top right of the first dash pic?  The orange wire runs directly to the white 12-wire harness
  • Did the 93s have a warning buzzer.  Mine has an aftermarket buzzer and light in addition to the OEM light.  
  • How can I clean the connectors in the harnesses?  I'm using a brass brush to clean the exposed terminals.

I would be careful on your nomenclature first of all- purple isn’t just “positive”, it’s keyed power. Anything that runs only when the key is on will be affected by this circuit. I would try not to daisy chain anything that draws a meaningful amount of power- gauges are fine but anything breakered/switched individually probably should be given a clean power source.

The only other bit I’ll mention is that I’d be careful not to bypass any factory breaker/fuse protection, and to make sure you’re adequately protecting your boat with breakers/fuses and wiring size choices.   The methodology you should be using to size wiring and breakers is to make the wire an adequate size to feed the current draw of the component it’s feeding, and then breaker a bit below the current handling capability of the wire.

Thanks for the initial comments...I went back and edited a bit in case someone looked at it in the future.  

I plan to use the existing breakers/switches and will be using wire that is the same size or one gauge larger.

If you, for some odd reason, decide to do away with your PP or decide to upgrade, let me know.

Plan sounds good to me

Where's the other end of the blue wire go to? 

They had a buzzer along with the light

Cleaning the female connectors, I usually use small drill bits or taps that are just a little smaller than the hole so I can do a little scraping of the junk (Along with your favorite electrical parts cleaner)

Larry - no PP on this boat

Ken - that blue wire is daisy chain (pos) for the gauge lights. It comes from the Nav Light breaker/switch. I’m betting the orange is for the curtesy lights.

Prev owner must have removed oem alarm/buzzer. Think I’ll leave the after market.

I’ll have to buy some contact cleaner.

I don't see any way to have a pizza and beer at that table, seems like a significant problem to me.

On wire size, I do think at times there's a tendency to oversize wires to correct the OEM dash deficiencies.  As I see it the problem is all the daisy chaining, which you are of course fixing, not that the wire used was all that undersized.  Better ground is always a good idea and it can never hurt to upsize that wire.

This may not be perfect but I would have liked to have been able to look at a pic like this.  (Red wires are (pos) in the pic…I should have marked). Will post an updated pic once I finish adding bus bars and removing some of the daisy chain.  Boat safe box to be removed.  Will leave original light and aftermarket buzzer.  Will hide or remove aftermarket warning light.

Re: wire size comment above: I am adding additional 10awg positive and negative to run in parallel with original.  Any new wiring I did to remove daisy chain is in 14awg instead of the factory 16awg.

Finished the dash pod.  Next is to run the new 10awg wires from the block and reinstall dash pod.  My wires are a bit messy around the breakers but I think it turned out well...hard to clean it up with the daisy chain of indicator lights running everywhere.  I also could have used some yellow heat shrink female spade terminals.  I needed ~4.  Oh well, the regular ones match from factory.  Double sided tape on the back of the bus bars

New pod:

Holy Moly, and I thought installing 2000 wood plugs in my Collegian was tedious.   Nice work David

Wired to engine and dash reinstalled. Horn is strong! Happy about that. Didn’t have the key with me so more testing to come but seemed that everything worked that runs off ign breaker.
