Well, I'd leave the wiring guides to folks that actually have the signals. Since right now this is envisioned as a community project, I'm not going to spend a ton of money to buy every signal possible to document them. 
Truthfully, this all grew out of the desire to have inexpensive signals, and in the other signal thread, we were discussing stuff like the WeHonest Signals, they have some decent looking signals for around $4/ea. The point was made that the control boards for these signals exceed the signal price by multiples, so the idea of an inexpensive board was born.
