When I was installing the flashers and horn on my Zforce 800 Trail I noticed that some connectors didn't have all the pins installed. I suspect the reason was to try and make the connectors different so that it would be impossible to connect the wrong plugs into the wire harness. In the end the missing pins didn't matter as when I plugged everything into the only places they'd mate to, everything just worked.
However, it would be nice if someone could identify type and source where one could buy the connectors and pins that are used by CFMoto so they could build their own wire harnesses for aftermarket accessory installs.
