CDS UNIT
 

I WANT TO REPAIR MY CDS UNIT CAN ANYONE TELL ME WHERE IN CAN GET A SCHEMATIC DIAGRAM FOR THE CDS BOX THANKS 77 911S

I doubt if a schematic for that CDI-unit exists anywhere in the continental US! But, even if you had one, without a factory parts list, you wouldn't very likely be able to fix it! Just order a Permatune unit, and be happy that a reasonably priced replacement is available!
