Okay ngl, im not that experienced. Lemme just send em a text for you they should probably text me back today night but as for the 5 to 1 connecter could you send a photo of what youre refering too? But I did find this on their website: https://www.amyet.com/products/amyet-ebike-main-cable?srsltid=AfmBOorhVdvEl30wrS9Yz9JUQkR_y4W0xdZ2Ab9FZBxA86sXXwR-Pekm but it is sold out for the S8 model so ill ask em about that too lol. Since it is sold out, I believ you can also order a few of this and work around it but if it doesnt work, worstcase you do just return them: https://www.amazon.com/AMYET-Electric-Extension-Waterproof-Throttle/dp/B0D7PYZZGS?th=1 But yeah imma give em a text rn lol and mb if I dont got the exact thing youre looking for
