This has happened to both of my jeeps. it's actually not even a problem. the caps on the battery corrode and make it hard for the cables to obtain electricity from the battery. all you need to do is take some sandpaper and rub the battery caps down until that corrosion is off and your Jeep will start fine.

On the brake pedal.

Stop light switches are mounted on the brake pedal lever, typically.

Should be located at the upper end of the brake pedal under dash area
do not take dash apart follow brake pedal upward and look for a switch that opens when pedal is depressed that is the sls.
