Recently I picked up a  ARN7 radio compass installation complete with all its accessories. I would like to use its wiring to connect my MN-62 receiver to the ARN7 accessories by the use of a conversion cable. I read that the ARN7 and Mn-62 are almost identical except for the connectors. 

On the Internet I could not find any technical information on the MN-62 radio compass. Anyone in this group that has a manual available? Only a wiring diagram would be of help as well.
