I used an app on my iPad called FreeForm created by Apple. It was not easy using an app designed for simple drawing and adapting it to create an automotive electrical diagram. I looked for specific apps for doing automotive electrical diagrams, and I could not find one that was created for the casual user. Any I found was specific for the professional and outrageously expensive. I did finally get it to do what I wanted, but not without a lot of frustration. It took many revisions and way too much time, but I did finally end up with what I think is a good result.
