I don’t recognize it but someone else might.

There’s a link to the service manual in my sig block. If you can download it there is an electrical diagnostic section and a wiring diagram.

Someone will come along knowing it but curious have you tested it to see if any power/reading to it?

could it be the connector next to the number 34 in this print , might be a power supply for accessories , it appears nothing plugs into it in the pic and from the dirt inside the plug , nothing has been plug in to it

There's power to it was a green wire black and green and red wire it had a rubber cap on it that melted

I think it's that 1 next to 34 on diagram but everything works just lights horn and rear break light starts fine and runs well just didn't want to buy a new harness just for front lights I got a light bar

Here a better pic

I was thinking maybe rear light wires , but with your new pic and the print of the rear light , I can see it is a two wire plug and the rear light is a three wire plug --------------- did you own this atv since new ? my theory is that it was an accessory plug that previous owner over loaded the wire with some electrical device

Looks like the accessories plug on my suzuki king quad

My buddy has the same rig, same year, I will see if i can check it out tonight.

 

[ATC4ever]

I don't see that connector.

 

[Noixz]

Haven't owned it since new everything working fine the lights was working but not snymore just found that burnt bit dunno what it is still

 

[fishfiles]

I had something very similar happen on the front end of a 300 Honda , the P.O. over loaded the accessory power socket and it melted wires all the way back to the battery and took out wires next to it , it was hard to find as you couldn't see the problem as the loom covered it , I could have done some repairs to the harness but just swopped the harness out ------- I am telling you this story as you might have problems hidden under the loom

I tried to get to the wiring diagram—the manual is 600 pages so scrolling with my phone a bit tedious.

So best thing would be for you to download the manual or get one, go to Chapter 25? Find the light, horn rear brake circuits a trace those wires—find where those wire colors tie in. You know the colors although you have a Bunch of wires in that thing narrow your search to the colors.

Maybe post a pic of the diagram for us?

Green is ground.

Thanks for that so much time on this quad fixed a few more burnt wires today but might have to have a look near the motor were the diagram shows where the lights run through still have that burnt plug aswell I don't know what it dose
