Number 5 and Number 8 above are great as is all the rest, but those two are what I consider the most important to me. Also after I had mine all done. I used small zip ties at intervals to hold the whole harness from moving around any while driving the car. If I needed to do anything it was easy to take a pair of cutters and snip the zip ties to let me move the harness a little. I also drew a complete schematic on paper of each wire and where it was ran and even the ones that went into the engine compartment. I had about 8 sheets of paper showing relays, wiring, and connectors in a loos leaf notebook but they sure came in handy after a year of so when I couldn't remember exactly where a connector was or which wire went to which relay.
