Nice drawing. What program did you use to generate the schematic?

There are specific apps and CAD programs that can do wiring diagrams, but they have quite a big learning curve.

I just used Paintbrush on my Mac. All you really need to do are lines, text and basic shapes. I actually didn't take that long. It's easy to do colors too.

One of the easier programs for creating diagrams is Fritzing. It's geared towards PCB design, but easily applicable to what you're trying to do.

I've been using Skycad for my wiring diagrams. Here's a low-res snapshot of what it looks like. Fairly large learning curve but easy to make changes.
