Sumitomo MT SEALED Series. 1 x 4-way FEMALE connector with sockets & seals. 1 x 4-way Female connector, 4 sockets & 4 wire seals (seals may be a different colour to the image). There are multiple types of similar looking connectors available, so i f in doubt, buy the MT 4-way Male & Female Set instead, and replace both sides of connection.
