And an older scanina that burnt out after the driver smelt burning under the dash lol
Yep, wiring is dangerous, but that fan wiring might only have drawn 20-30A and was a fire risk.
A friend had a rear vent thing fitted to his van years ago for the dogs, the people who fitted it never fused anything and 2 days later the van went up in smoke.
But again low current anyway.
So a 200A or 300A fuse ? Really isnt going to offer the protection you think it might.
use good quality cable, terminations and route the cable as safely and securely as possible.
ie for me that means either inside or at least somewhere not around the perimeter of the vehicle that might be most vulnerable in an accident.
