[LS short box]

I don't know what level of project you are doing but on my project I filled the original fuse block hole and then moved the Painless fuse block back a bit from the firewall using a "L" bracket I fabbed. Then I ran all the chassis wiring over the top of the steering column and then made hole it trans tunnel for the wires. Ran the wires forward and back as needed. On my truck you can't any of the chassis wires.
