Working on a friends 500SL. Power antenna not working in the car as it has no power cable going to it and I cannot seem to find the cable. I bench tested the unit and it seems to work, just needs a new mast as the old one was ripped out in a car wash. I am attaching two pics of the amplifier hoping someone can tell me where the output is for the antenna. Any advice is extremely appreciated.

 

Found the Hirschmann Control Module and it is smoked. I'm guessing there should be a two conductor cable from the module to the antenna?? Where is the best place to find a replacement module?
