ive got a 110 cc atv and i dont have a wiring harness just the wires from the engine and the spark plug leads, how can i get spark?

 

Well I've got bad news. You need a wiring harness, and a lot of other stuff too - like a CDI, ignition coil, starter solenoid, kill switch, ignition switch, voltage regulator, fuse, battery, and these all have to be wired up correctly. This is a *BIG* job.

You could make your own wiring harness that eliminates stuff like lighting, and startup safety interlocks, but that ancillary stuff is only about 10% of the wiring. Wiring up the 90% *required* stuff is (like I said) a *big* job.

I'll help if you are determined, but at the sme time I don't want to give you any false hope. Some have been succesfull at doing this lately, but only a few. Are you up to this?
