Currently running 2 12V 40000 motors and man it runs like a beast ! Been running for a whole year and we abuse this tiny car ### ⭐⭐⭐⭐ Good, but not plug and play *by N***S on October 6, 2024* I used this kit to repair my child's ride on toy that had a bad controller board. Because it was an off-brand there were no direct replacements so I decided to just replace everything. Overall, it seems better made than what the car came with. However, a wiring diagram should have come in the box rather than just the Amazon listing. Unless you have a model very similar to this one, this is a kit for someone comfortable crimping/soldering wiring terminals. Mounting the switch gear and running new wires is a project in and of itself. The end result seems good. I'm also running an 18v power tool battery conversion kit and it seems to handle it just fine. ## Frequently Bought Together - POLYNX 12 Volt Power Wheel DIY Modified Wires,High Power Self-Made Children Electric Car Wires Harness and Power Wheel Remote Kit Weelye 2.4G Remote Controller Kit Ride On Replacement Accessories - weelye RS380 12V Steering Motor for Remote Control Car, Children Electric Car Steering Gearbox with Motor, Children Ride On Car Replacement Parts - ExpertPower 12v 7ah Rechargeable Sealed Lead Acid Battery --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/486296746-12v-diy-modified-wires-harness-for-power-wheel](https://www.desertcart.hr/products/486296746-12v-diy-modified-wires-harness-for-power-wheel) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-03*
