Yes, as many reviews say, there are no instructions. However, they are identical to Anderson Powerpole connectors whose assembly instructions are easily found online. If a particular buyer can't figure it out, that doesn't make the product bad. In short, each contact has a convex side and a flat side with a pronounced step. This step should snap the metal spring built into the fork. Insert the flat side so that it touches the spring; it will click and you will understand that it was assembled correctly. Easy.BTW, you can crimp them with most hand crimping/stripping tools. Use non-insulated sponge 12-10; It can puncture, but it secures the wire (mine was 8 gauge) and provides enough contact. The parts, including the covers, are well made and securely fastened. Please note that the back of the connector is not waterproof. At the rear, where the cable enters, water can enter at any time, regardless of whether the plug is installed or disconnected with the caps installed. worth your money.
