The fuses for the chassis should be on the fire wall in black boxes. If not there; then under the dash. It will not be fun to get to.
Tip: pair of small needle nose pliers
assorted ATC mini fuses
Once you get under there you will want to have everything you need, one time!
Also, check to be sure the wiring on the brake switch, did not get knocked off.
