I have the SC-810 and SC-811 radios. The connector coming out of the back is apparently for a 960. The 960 has different color wiring than the 850. Do you guys know of a diagram or if theses can work together. I have not been able to find the connectors for an 850 on the web. The 960 connectors correctly in the back. I took it to an audio pro and he did not know.

 

Actually it may be a 940 and not a 960... though 960 sounds right. I just wanted to throw that out there.
