Adding second 80 amp fuse.
I need to add power to a accessory fuse block and noticed that it looked pretty simple to add a second fuse next to the stock 80 amp fuse.
Looks like all I need is to upgrade the existing feed from the battery, pick up a new fuse and another brass screw. Seems too easy. Has anyone done this before?

Interesting idea. I have added a 2nd cable to upgrade the line to the alternator (part of big 3 upgrade), but I didn't notice the slot for another fuse. I purchased a 100 amp inline fuse for my extra fuse block.

There is a space for another fuse next to the main 80 amp fuse, but if you add another fuse there it would be a real good idea to upgrade the power wire from the fuse box to the battery with a heavier wire. I would go with at least 6 gauge battery cable at a minimum, the stock wire is 8 gauge.

It looked simpler to add a wire than to replace the factory 8 gauge. It is crimped to a brass plate that connects both sides of the fuse block. Toyota chose not to run the headlight circuit through the 80 amp fuse, which makes sense to me. I wouldn't want to lose both headlights if 1 fuse blew!

Anyhow, I would be concerned that the wire connected to that 80 amp fuse can carry 80 amps. That is the point of having a fuse: the fuse blows before the wire burns.
