headligh problem

Hi guys, I have a 91 LS and my passenger headlight isn’t working. I checked it out and it seems fine but I bought a new one anyway and replaced it but it’s still not working. I checked the fuse under the dash and the one under the hood and they’re both fine. I also checked the wiring ito see if it was loose or anything but that seems fine as well. So, guys what do you think is the problem? Thanks!

There is a break in the wire somewhere if it is not the headlight plug. Had the same thing happen but the plug was bad and had to replace.
