First post here and hoping to get some help as I'm new to RC truck building. Recently finish my first truck, Grand Hauler and I want to wire up my dump trailer using the MFC J9 port, IT's a three pin JST, but are there different types of JST connectors?
After Googling it looks like there are different types, anyone know what type is used on the MFC?

Thanks,
