does anyone have a a/s with the original braun auto ranger electic tv antenna. My 73 excella had one but the PO removed it and put a manual crank up unit in it's place. I have a newer electric model and would like to replace the crank up unit . I am wondering about the wiring for the old unit. The original control panel is still there. Does anyone know what the various wires connect to. Anyone with a owner's manual or service manual a copy would be a great help. Please see pics.
