I'm not sure which connector you are looking at, but all wires are held in the connector body by a locking tab or strip. You may need to get a magnifying glass to see it. It would be helpful if you could supply a few up-close photos. Good luck.Hello everyone. Currently replacing a wire harness pin connector #47 which is housed in the X3 terminal box of the underhood fuse box. I cannot get the wire to slide out of the terminal block. Any tricks to this procedure?
