Tail light wont brighten with rear break.

[GZeachCruiser]

Hello all,

Brand new to the forum and the GZ world. Just did a bunch of work on the bike and will be posting photos soon for fun.

So I was cutting off my muffler to install a new one and accidentally cut my rear stop lamp brake light switch cable. I ordered a new one and installed it but now my break light wont light up when I use the rear break. It does however light up with front break. I am curious how the cable engages the light in the first place.

Anyone know whats going on here? I assume it will be something small I am not noticing.
