Using these cables is easy. First, locate the inline socket and plug connector on each cable. Align them properly and push them together until you hear a click, which means they're securely connected. When disconnecting, just pull them apart gently. As for maintenance, keep the cables away from sharp objects to avoid cuts. Don't expose them to extreme temperatures or moisture as this can damage the connectors. If the cables get dirty, you can use a dry cloth to wipe them clean. Remember, these cables match with each other and any Molex PicoBlade compatible connectors, so feel free to use them in various setups where you need a light and small connectivity solution.
