I have a tether switch but it just came in a bag with no instructions on what wires to hook this thing into. I'm entering a race on the 16th and need it to enter. Any help would be appreciated.

What kind is it? i think most of them hook up into one of the coil wires somewhere, but other wise i wouldnt take my advise on this one, because im not sure

If I am not mistaken, it connects to the black and white wire (shut off).

The original kill switch has to have a black/white wire. That wire usually goes to the coil. Disconnect that wire and connect it to the tether switch.

Yup, black and white wire
Should i tap into the wiring up around the on/off switch on the handle bars??

Yep,
One of the wires must be connected to a good ground.
The other tap it to the existing wire coming from or to the ignition kill switch.

Now you are ready to crash and have piece of mind knowing your quad will shut off and wait for you to get up and keep riding

Right on....gonna hook it up tomorrow morning. Thanks for your help Sandpusher

STILL NEED HELP~~
I pulled the kill switch apart and found the 2 wires.
tried connecting the tether to the brown one and ground...blew a fuse
tried connecting to the other wire.....blew a fuse
????????
i'm stuck and don't know how to hook up the tether switch.

Ask effinbees77, he know how to, he has directions he saved, im gonna get one soon if my parents let me race and ill need to hook one up to, but pm him and ask him how

effinbees77 is out of town for the weekend. I don't know that he will see a PM before Monday, if you need it for tomorrow I will call him and ask him to respond to this post. goood luck.

That would be great guys!!
My 1st race is now cancelled for tomorrow, due to the heavy snowfall we've had here a couple days ago.
Ozzy or Shocker if ya see effinbeez let him know i'm still stuck!! Thanks in advance for all your help

effinbees77 said that he believes the yfz needs a harness specifically for that bike and asked if you posted at yfzcentral. he wil get on here tonight and maybe help you out. good luck with this and the race. if only i could get a kill switch hooked up to the 185s i would be out there with you.

Thanks guy.....check your rep

If I had the bike in front of me I could help you.
I have lots of electronics experience being an Electrical Engineer.

If you know basic electronics and have a multimeter (a cheap one will do), take your current kill switch appart, I can walk you through each step to determine which cables to connect or disconnect.

I have a raptor, but I am not sure if the kill switches are the same or alike.
As soon as I get home today, I will open my switch, and let you know how mine works.

Bronc, try this page it has step by step for the YFZ. Hope this helps. Haz

I'll give the wiring coming from the coil a shot. If there is a solid white wire, that should be the one!! It's monday morning, i'll try tonight to see if it'll work.
Thanks Haz

im putting mine on my 2 wheeler this summer... bought it from rockymountain atv and never put it on... i can send you a copy of my instructions... its a 2 wire setup like yours...

I just hooked up a rope to the spark plug wire. I fall off, it comes off...

That's gotta be the best Hi-jack post i've read yet

F.Y.I......YFZ450 has an orange wire and a white white coming from the top of the spark plug. Under the front cowl where the mess of wires are you'll see the 2 wires there with a black connector. Tap into the white wire with the white wire on the tether then ground the black wire. 3 hours of trial and error and 10 blown 15A fuses , but i figured it out!!!
