Default JEEP Cherokee Brake Lights

Again, you didn't give the year/model so I can't be sure which switch
you have, but on my 88 and the son's 91 the switch has a two-wire
lead/connector that plugs onto the switch itself. On his, he has a
third tab connected to the open side of the switch that is referenced
in the FSM as being for the auto tranny only. I also have the third
tab with a 5-spd but it is simply sitting there with no connection.

On those larger connectors you sometimes have to "reason" with them -
they have a locking tit on the lug that drops into a hole in the
female side and they can be pretty tight to get off. I use a thin
screwdriver to pry the connector off - carefully.
Since you are working with one lead hot to the battery, you might want
to pull the negative cable before doing this unless arcs and sparks
don't bother you.
