Identifying *Spare* Plugs

[Descolada]

Hi All,

So I am continuing my mammoth maintenance and additions project. Just completed the maintenance tasks and am about to move to additions  

I was also continuing general cleaning as I go along and found myself sitting looking at the nearside of the bike. I had been in the process of cleaning off some rather unsightly grime and crud from the electrical harness and associated plugs when I realised that I seemed to have some *spare*. As well as general interest I wondered if I could make use of these for any electrical source connections.

Here are the three plugs in question;

I think you'll find they are some kind of bridging connectors. Try using the search box on the top right. It will lead you to most of the topics you need.

Plug 1 is the plug you would use for dealer mode or connecting a Yoshi box or such, it's the ECU connection plug.

Plug 2 is a jointing 'block' for several earth wires and not really a plug.

Plug 3 I'm not 100% sure, but I think it is used for the Suzuki/Acumen alarm connection. Greywolf can probably confirm/correct me on that.

The one with all black wires is a diagnostic plug. USA bikes don't have it. The dealer mode connector has six openings for four wires including a white/red and a black/white next to each other. The third is also a connector I've not seen, not only on USA bikes, but in the wiring diagram for Euro bikes. A connection for an accessory like an alarm would make sense.

Wires shouldn't get hot...

[greywolf]

This may be the only wiring thread I've ever done where I did not talk about a hot wire. I know "earth" is used in the UK for the negative wire I would normally call a ground wire. Do I need to use a different description here from "hot" to describe the positive wire?

[Juvecu]

I'm messing with you, mate You frequently use hot though. I notice it every time because I used to work for American Power Conversion (APC) and because the UPS units were all designed in Rhodes Island they use the term "hot" instead of Live/Positive. I have no idea if most others on here are familiar with the term or not.

On some model Suzuki's the plug with the 4 black wires is used for connecting an alarm. If the socket has a plug in it you will see that the plug shorts out two of the black wires. Don't know if this applies to the DL.

Let's change the filter to switch from "hot" to "live".

Then we can come up with such gems as "hot a-s-s" turning into "live donkey".

I am just here for your amusement

According to the wiring diagram, plug 3 is connected direct to the ECU. I think it may be used for remapping using something like a Yoshi box but would welcome more info.

For reasons that escape me some previous owner has chopped off plug 1 leaving the wires waving in midair - I intend to fit a switch so that dealer mode is instantly accessible.

[Juvecu]

Ian, there's a live on that so best make sure they are insulated.

[iansoady]

Yes indeed - they're actually quite short so I don't think there's too much risk but it is around number 7 on my list of 50 or so....
