Went to install my LED headlights and run into a little issue. Installed the two center headlights with no problems. Took about ten minutes. Started on the outside lights and the trouble soon began. Removed the rubber boot, disconnected the ground wire. I can not get the power wire (yellow) to disconnect. I have pulled and pulled but I can’t get it loose. I am afraid I am going to break it. Is this connection crimped on. It looks like it should pull right out. What am I doing wrong?
