This is a wire harness for the CB01 series, a 2.5mm pitch waterproof connector for relays from Minebea Connect (formerly Sumiko Tech). The CB01 series is a small, highly reliable 2.5mm pitch waterproof connector. The terminal is pressed into the wire seal built into the connector and held in place by a retainer to ensure waterproofing. The product in the image uses CB01A5-03B0-02 for the relay M housing, CB01C5-020A for the M terminal, CB01E0-01N0 for the waterproof plug, and UL1007 AWG22 for the cable. The cable is covered with a shrink tube.
