I've been modifying the 1MZ, 2MZ, and 3MZ platforms for years, and it's no secret that the main thing holding many enthusiasts back from unlocking their potential is the lack of aftermarket support, especially when it comes to tuning. It's frustrating. In 2025, we shouldn't have to struggle with custom wiring a standalone system or trick the computer just to tune these engines. There are countless enthusiasts out there, like me, who crave more power and control but face significant barriers because the necessary support just isn't there.

We're passionate about these platforms and are ready to invest in improvements, but tuning these engines remains a daunting task due to the absence of plug and play harnesses from major suppliers like Haltech. Custom wiring is not only time-consuming but also prone to errors that can jeopardize the performance and safety of our vehicles. It's high time that our needs as a community are recognized and addressed.

The 1MZ, 2MZ, and 3MZ platforms have a dedicated following, deeply invested in enhancing their vehicles. The development of plug and play harnesses would be a game-changer, reducing modification complexities, increasing accessibility, and helping to foster a larger community focused on these amazing engines.

By signing this petition, you'll join me in urging Haltech to recognize the market demand for plug and play harnesses for the 1MZ, 2MZ, and 3MZ platforms. This development has the potential to revolutionize how we modify and enjoy our vehicles. Make your voice heard and help bring about the change we desperately need.
