The factory uses a 10amp fuse from the battery to the pcm on the orange constant wires and a 15 amp fuse on the ignition voltage to the pcm.

Use the fuses, they are cheap protection incase of a short.

What he said. ^^^

I wired in an in line fuse holder for the 15 amp fuse off the orange wire to the PCM just in case. You can get a single fuse in-line fuse thing at Autozone or store like that.
