I have a couple remanufactured Bosch ECU's, part numbers CU-10X and CU-13X does anyone know where I can determine what vehicle they fit?

cu13x appears to be 1.7 and 2.0 1972/1973 914 engine. Don't know about the cu10x, I can find no reference on it. Got a part number? http://members.rennlist.com/pbanders/djetparts.htm Other VW ECU cross referencing: http://www.type2.com/library/fuel/fuelibo.htm
