What's wrong with running all the switched ignition wires together, they all do the same thing. It WILL have a fuse block that the main ignition on/off will run though and that the battery constant power wire will run though as well.

The pcm feeds cant take more than 10-15 amps from a direct short to ground, Running the PCM,(8)Coils,(2)O2 heaters,(8)Injectors,& a MAF sensor on the same fuse is asking for trouble. What AMP fuse are you planning on using?

NOT really the proper way to do it, why dont you show us something new or helpful and not just following what other websites recommend so you can get famous on you tube.

Hey man, not trying to get famous just having fun with video editing. The reason I made the videos was to show people what was exactly involved in redoing a harness. As far as I know I have never seen any videos that show much about these harnesses and how to work with them. I now realize that we did do some things wrong and I should have separated out my positive wires so they can be fused separately as clinebarger pointed out. This was the first harness I did with all the wires together. Other than that what the heck did I do wrong? I've done a couple of these harnesses and never had a single problem.
