Hello, all! Just purchased online a used NA12S Suzuki side mount control box with cables and main harness to use with a recently purchased DT65. Have searched online without success to try to find a set-up manual for this (or similar) control box, and am therefore hoping I can get some answers here. I have attached several pics to help clarify my questions. Any help will be appreciated!
1. The box has a short harness with 6 bullet type connectors - from what I have seen in online pics, 4 have (or are supposed to have - see below) connectors in them with "nail heads". Where / for what does this harness connect?
2. One of the "nail head" connectors is broken on my unit. Are these available separately? Can anyone provide me with a part number? I have looked at all of the parts pics I can find, and cannot find either the harness or the "nail head" connectors.
3. It looks like these "nail head" connectors simply pull out, bullet connector style. Am I correct? Don't want to force and break anything?
4. I was told before purchasing that it did not have a key....BUT... the switch has a plastic cover over it, that doesn't seem to want to pry off. Yes, I tried, but, again, I don't want to break it. (See 2 photos.) Is this just a key-hole protective cover that is supposed to snap off?
5. The safety lanyard connection (my unit did not come with a lanyard) has a plastic cover. One of the pics shows the connection with that cover removed. Does this look correct to accept a safety lanyard? Always a good idea when in choppy/rough water or out by oneself.....
Thanks,
David

I would edit my post above, but cannot because of the 1 hour time limit iboats has implemented.
I have answered some of my questions.... by closer examination and fiddling.
Turns out that the "nail head connector" things are not connectors at all, simply plastic plugs that ..umm.. plug into the harness. Insulators, of a sort. I guess the nail head is just there to make it easy to grasp. (Hey, they are old and discolored.... looked like metal, not plastic. Sorry!)
I am thinking, without knowing, that this harness (the short one with the nail head plugs) is for accessories/gauges like trim gauge, tachometer, etc. Sure would love some confirmation on this.
I noticed that the cap on the kill switch has a pin inside in the center...plus realized that the cap has a hole in it to attach a safety lanyard. So, I figured that one out. I am good to go for the kill switch issue.
Still looking for help regarding 1) the 6 bullet connector harness function AND a wiring/install/setup manual for the NA12S (I think the NA27S is essentially the same), and 2) some insight into the ignition key slot cover issue.
Thanks...
David

Found a wiring diagram showing the wiring for the short harness on the control box. It is for gauges, as I suspected. Am attaching in hopes it may help someone else!

Still looking for insight about the ignition key cover......

Thanks, mphelle8vld. I guess what I am confused about is that this box has no visible key slot. Just the little round hole shown in the lower right picture, which is in the center of what appears to be a cap - per side view in upper left picture. Is this just some type of protective cap that pops off? It's got 3 little tabs on it, as shown in the two referenced pictures. I am afraid to apply too much force ...fear of breaking it, of course. Any thoughts? Thanks!

There is no key slot, the key will be shaped just like the safety lanyard cap. Couldn't upload a photo of mine, the safety lanyard cap is normally red so there's a chance that the cap in your photos is actually your ignition key.

I have seen the keys online, so I know exactly what you are referring to about looking like the safety lanyard cap (when in the ignition switch). I guess i will just pry off the cover.... for better or for worse! LOL And, I also know that the key code will be on the cylinder...so i have to open the unit up, which of course is no big deal. Thanks, again!

Looking at your bottom right photo, the ignition switch is on top, there is nothing there to pry off, the key (cap) will clip over that switch. On the bottom is the safety lanyard switch and it looks like an ignition key has been jammed over it. Let me know what you find.

You may be looking online at the keys for the newer version controls

No Title

Your comments proved to be exactly correct, thank you, mphelle8vld! Yes, it turns out that it IS an older (88-92) style control box. This box, as opposed to the 93-97 control boxes, uses a MAGNETIC key! What the hey? Your comments became exquisitely (? LOL) clear once I pulled the switch from the box, and saw the number (106) stamped on the side. Actually kind of double stamped - makes it look like one is looking at it with extreme astigmatism - made it difficult to see the number, but looked at it (and took pics so could "magnify" from different angles and different light angles. Once I saw the key number, i then used your provided link to get the part number, and checked Ebay... and found 2 listings, both with pictures, one of which i attached here.

Silly me...I was expecting it to have a bladed key (can you say "normal"?) ... So now your comments of "There is no key slot, the key will be shaped just like the safety lanyard cap. " and " there is nothing there to pry off, the key (cap) will clip over that switch" makes perfect sense. I was stuck in a mental rut, as it were, assuming that the key would have a blade. Just needed a paradigm shift for your comments to "fall into place".

Tried the safety lanyard cap on the ignition switch, without luck. The pin inside the safety kill cap is plastic... so no magnet. I wonder how they code the magnets? Hmmmm... well, no matter, as long as it works. I DID order a NEW 106 magnetic key, so should know within the week.

​Reading back over your comments, they were ALL actually very accurate and descriptive. As I said, I was stuck in a mental rut of predisposition. I ASSumed that it used as bladed key....but then, ya know what they say about "ASSume makes an ass out of u and me". Well, me, anyway!

Will update when the key arrives.... Thanks again for your accurate insights and detailed descriptions!

David

I was dancing around the part where it's a magnetic key without a traditional metal blade, I've had mine so long it seems normal. What's the history on your motor?

Made me laugh out loud about you "Dancing around the part where it's a magnetic key without a traditional metal blade". Well, I am DEEElighted to have the mystery solved and a key ordered! Thanks again for all of your helpful input. The history on my motor is .... ummm... not good...but it will get better. Will answer by a new post, so I don't get "moderated" for hijacking this post. Look for "DT65 water in lower cylinder"
