Is there a trick to the electrical disconnect? I really feel if I pull any harder I know I'm going to break something really expensive. I even tried the clip first and that's a joke. I'm taking a break and my fingertips are killing me. What am I doing wrong?

I'm replacing the left side now, but beause I bought two H7 Silverstars, I'll next attempt the right side. Looks like I have to remove something first...
