There might also be a smaller fuse block inside the car, often located under the dashboard, but the main fuse box is under the hood.
To be absolutely certain, you should:
* Consult your owner's manual: This is the best resource for precise fuse locations and diagrams.
* Check online resources: Websites dedicated to classic car restoration or Dodge Challengers may have diagrams or photos of the fuse box. Searching for "1972 Dodge Challenger fuse box diagram" is a good starting point.
Remember to always disconnect the negative battery cable before working with fuses to avoid electrical shocks.
