I ordered these JYFT Solar connector wrenches to work with JYFT Solar connectors. When I connected the MC4 connectors, they are quite difficult to disassemble. My fingertips can only do one or two at a time. Likewise, attaching connectors to wires is very rough on hands after you've done the first one. These tools make it so much easier! They come in a set of two: use one wrench on the connector body and the other on the strain relief nut to assemble. At the other end of the tool are two "fingers" that you use to squeeze the latches on the connectors to separate the two connected ones. Having the right tool for each task makes it a lot easier.
