So, while I knew that 4 wire really just used the old UART signaling to operate, with modulation added, it was a simple case of finding the UART TX and RX lines.  

Luckily the old radio guys who designed this enjoyed using dedicated chips.  Aside from the technical ease of using these types of ICs, the dedicated chips also were less prone to radio noise in a high RF environment.
