After spending way more than I ever thought I would on this so called cheap nitrous, I have got all the plumbing in place and now am on to the electrical. As bad as I thought the plumbing was, the electrical will be much worse.
Below is the way I am wiring it up based on me having to use the trans brake.

It doesn't look that bad to me but then again, I remember you saying you're color blind and I don't know where all your relays/fuse box is located. Plumbing for me has always been the biggest challenge....I always seem to have 1 leak somewhere that's always hard to get to. Just remember this, electricity doesn't leak, so as long as your connections and grounds are good and it's all wired correctly there shouldn't be a problem. I've been using di-electric grease on all my connections lately to prevent any corrosion problems in the future, especially on the ground side. Good luck! Holler if you need any advice.
