It groups every major component you normally need for a full electrical replacement into a single package, saving time and compatibility guessing compared with buying parts separately. Before purchasing, check your engine family — this kit is not compatible with GY6-style motors or larger 150cc+ stator\/CDI systems.\u003c\/p\u003e\n\n\u003ch3\u003eWhat components are included and why does that matter?\u003c\/h3\u003e\n\u003cp\u003eThe kit supplies a full set of electrical parts so you can replace a damaged harness and associated ignition components in one go.

This kit is aimed at owners and mechanics of small four-stroke ATVs, quads, pit bikes and go-karts who need a single-source electrical replacement. If you run a Chinese-made 50cc–125cc upright engine and want to restore charging, ignition and switch functionality quickly, this comprehensive set saves parts-hunting and reduces installation time. If your machine uses a GY6 motor or a 150cc+ engine with a different stator\/CDI layout, choose a kit built specifically for those systems instead.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this wiring kit fit my 125cc ATV?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes if your ATV uses a Chinese upright 125cc engine with the matching stator\/CDI pinout; it does not fit GY6 or 150cc+ stator systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I install this kit myself?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: A competent DIYer can install it using plug-and-play connectors, but professional installation is recommended if you lack wiring experience.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"JingSney","offers":[{"title":"Default Title","offer_id":48086104408222,"sku":"B0G66QHGSS","price":48.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/jingsney-harness-front-packaging.jpg?v=1785884975","url":"https:\/\/northtrailauto.ca\/products\/jingsney-wiring-harness-kit-for-50cc-125cc-atvs-dirt-bikes-complete-electrics-set-with-cdi-ignition-coil","provider":"North Trail Auto","version":"1.0","type":"link"}
