Hello all, Have an old Escort radio lying around and would like to get it to run in the basement. It has 9 connections on the back. (1 for antenna, 4 for 2 boxes) For what are the others, or what of them is mass etc. I don’t know exactly what kind of radio it is on the side says: Ford ESRT 22 DPS, otherwise there is nowhere else. From the front it looks exactly like this one http://cgi.ebay.de/…5QQcmdZViewItemQQptZCE_Auto_Hi_Fi_Autoradios?… However, instead of the Tone and Bal Turn knob only a rotary knob without labeling there. Does someone know what the radio is called and how to plug in the rest? (have no adapter has to plug in the cable like this) Greetings Simon
