We use alot of HID i-class readers, if that helps, the colors on a 5-wire or 6-wire or etc. are pretty standard, most of the info you'd want is in the gateway user's guides and possibly the quick start guide. But for the answers on more detailed proximity info or the 26-bit/34-bit differences you'll need more help, i suggest also HID themselves if Cisco forums does not offer up your answers.
