2012 Vulcan 900 - rear wiring question

2012 Vulcan 900

Does anyone know the name/model/part number for the connectors under the seat for the tag light, tail/brake light, left turn signal, and right turn signal?

I searched the service manual and found a wiring diagram but none of the connectors are marked.

They are not physically the same connectors. You cannot mix them up.
They are not interchangeable. Just unplug them to find out.

The tail/brake connector has 3 wires.
The others (both turn signals and license plate light) have 2 wires each.

The wire colors from the diagram can help though you might not be able to tell from the sheath.

Good luck with it.

The connectors do not have part numbers that I could ever find. I am sure there a catalog item, but not Kawasaki's catalog. They come attached to the light assemblies. If you have a broken or damaged one, you might have to get a weatherproof connector to just cut off and replace it.

Thank you for the diagram. I'll save a copy of that.

I tried the local Kawasaki dealer today and the do not sell the plugs. Clearly, they are manufactured by someone but not a part number I could buy from the dealer.

I'll just cut the old wires off the original lights and splice in the new lights. I was trying to keep the old wiring under the fender intact.

Most plastic modular connectors are not company or model specific, Kawasaki might not even make the wire harness it installs, it could be subcontracted out to another company. The connectors can be found though, but not easily. They are made by companies like Molex:

Your best bet is to do a google image search for something like "plastic 2 pin connector" and start finding what looks like the connector you need. Be warned though, for crimping the contact, most will require a special tool. Personally, I like using pre wired Weather Pack connectors with epoxy solder sleeves for the wire to wire connection. The connectors and solder sleeves can be had for pretty cheap off some place like Amazon. It makes for a nice weather resistant connection that can easily be separated if needed.

Rules to live by:

Never trust a fart after a night of fast food.
Never take a laxative and a sleeping aid on the same night.
When riding, wear gear you don't mind having a wreck in.
Don't ride above your skill level.

Vulcanbobber2019, don't cut anything yet. The websight to go to is easternbeaver.com. Goto Main page, then click on Connectors, then click on this connector type,. "HB/HC .050". There is a male and female 2 wire connector, and a male and female 3 wire connector. There are also extra pins you can order. These connectors match the Vulcan 900 light connectors exactly. You have to order at least $10 worth of stuff, but that's no big deal to do. This is for turn signals and brake lights. You will need a crimper for the pins also.

Just found this on accident. Looks like factory connectors that are pre-wired, no need to purchase a crimp tool. Just FYI for future reference.

Guys, those are great links. I will be saving them for reference.

I cut the wires from the original harness under the fender and splice in the wires on the new lights.

I will try to research the sites you shared and see if I can purchase the pins. If I can I'll order the pins and clean up the installation further.

Attached is the project after working on it this weekend.
