I recently purchased the 89661-35N61 ECM for my 2018 Toyota 4Runner, and I couldn’t be happier with the experience. The unit arrived quicker than I expected thanks to their very reasonable shipping costs, which was a pleasant surprise. What really stood out was the plug-and-play setup—the module was already VIN programmed, so installation was straightforward and hassle-free. My 4Runner fired up perfectly right away, no glitches or issues. The whole process was smooth, and I appreciated not having to deal with complicated programming on my end. Highly recommend this product and service to anyone needing a reliable replacement ECM.
