Buying a used bike is always a surprise. I removed the seat tonight to attach an SAE connector for my heated gear and batter charger. I was surprised to see these loose wires





Can anyone tell me what these are for? Thanks.

Can't really tell from your pic but I think they're aux power in the upper pic. Is one hot with the ignition on or just hot and one ground? Not sure about the bottom pic. The wiring diagram may show where they go.

If you take the connectors off and splice the two together, it unlocks the super-fast mode of the bike where you get an extra 32 hp and 54 tq. ;)

Just kidding!! Don't do it. There are quite a few wires under the seat with seemingly no connection. I'm guessing Kawa used some standard wiring harnesses for the Vulcans and some items just aren't used on our's. Maybe?

The problem with wiring diagrams is that they don't tell you the physical location of the the items in question. Of course you know where the lights and switches are located, but not a certain relay, etc.

The bike runs fine and everything seems to work so I will investigate further when I have the time. I was just hoping someone had allready figured out what these were for.

Get the shop manual, all the electrical componenents locations are shown. They even have pictures. An unused connector doesn't necessarily mean something is missing or that it should be connected to something.

Our ZRs came from the factory w/ aux non-switched leads; perhaps your bike did as well and the top photo shows them? Don't have a clue about that empty cannon plug unless it's for a California or other differently-spec'd bike, or perhaps for factory accessories yours doesn't have?

The cannon plug may be for a diagnosis machine and the other 2 look like stock Kawasaki accessory power wires.

Man, that was the best mod ever!! I didn't even have to fire the bike up, and it roasted not only the back tire, but the whole bike!!!

J/K

I'm pretty sure I have the same crap under my seat, doesn't seem to hurt anything, so I never bothered looking for an answer.

Ok. The wires in the first pic are definitely accessory wires. Still have no clue what the plug and wire in the second pic are for.

If memory serves me correctly the bullet connector (top connector) in the second pic is used to diagnois the ECU. To do this you simply ground this connection and the FI light with flash codes, when the ignition is switched to the run position. You should refer to the service manual to verify this. As for the second connector in the bottom pic, dont know, have never needed to know. I would suspect that it may be used for diagnoistic equipment. The spade connectors in the top pic are for accessory connections, pos+ and neg-.

I'm not sure what it is but its not PCIII. The only "ends" you will have with a PCIII will be under the gas tank (just installed one today!). The wires cannot be disconnected from the unit itself as they are not connected via wiring harness, etc that could be undone.

The wires in the first pic are accessory wires one end is under the seat near the battery and the other end is by the steering head. they can be used for whatever you need to get 12v to the front of the bike. GPS, Ipod, heated grips, etc.... They dont work for the SUPER fast mode anymore. They stopped that in 06 for EPA restrictions):poke:

The second pic is the diagnostic computer plug in port.
