installation

Hello, some guy in the post office forced himself to help me up 3 steps, he grabbed my throttle and broke it… I’ve bought a new one, 6 pin like the last one. I cannot find the OG brand replacement online, even on the company website. In which order should I put the coloured wires? Both are...

So I have a new rear wheel kit. Trying to fit a 7 speed shimano freewheel and there is no clearance? The washer hits the cog please see images? Am I missing some proper spacers?
