How do you wire a fuse in series?

 

It's the same way as you would normally wire a fuse, just put another one on the same line... just like the little picture thing above.

And hondaman is correct about the parallel/series thing.

 

Ah gotcha.

So what was your idea with the fuse holder?

 

I was going to do a fused distribution block under the hood to fuse only the stereo stuff, then run to the ABS, starter, and fuse block somehow. Now, I'll just pull off the battery terminal under the red cover like you said, go through the above fuse and through the firewall.
I'll post pics when I get it installed. It's kind of hard to explain.

Thanks again for all the help guys!
