I'm with "doc41". I believe that having current proctection is very important but hiding that protection under insulation and such doesn't get it with me. I've read that new car manufactures are moving away from them. I trust my ride to the same wiring techniques that protect my house and most likly yours. The fuse is to protect the wire downstream from it. The wire upstream will handle the the current necessary to "pop" the fuse and other feeder circuits. A fuse/breaker are easy to troubleshoot and replace if necessary. This "argument" extends to the redundant relay issue with cooling fans and such. If one relay of two in parallel feeding a cooling fan goes out there is no way to trouble shoot it short of removal and testing. I don't run two cooling fan relays, two brake light switches, two relays for the headlights, etc. We're not flying the space shuttle here.
