In a production harness that gets mated once and then lives in the vehicle, that's fine. The blue insulation color is a visual key on the assembly line; it matches the Micro Quadlok series coding.","metaTitle":"953118-4 TE Connectivity Micro Quadlok Header, 40 Pos","metaDescription":"953118-4 TE Connectivity AMP Connectors Micro Quadlok header, 40 positions, 2.54mm pitch, shrouded, friction lock, tin contacts, -40 to 85°C.
