There are OEM fuses in my Grand an inch or 2 in front of the radiator. Generally anywhere you can put your hand without burning it will be fine for a fuse. That includes most engine compartments where things arent touching the block or exhaust.For years tractors had fuses along side the engine.
Modern cars have the large fuses in the engine compartment.
In short, no problem

My fuse panel could easily be hooked to a relay to make the entire thing switched. I just didnt see the need, but it installs nice and clean and is weather resistant.View attachment 500438
