[928uk] Radio wiring and books

[Donald Peach]

Have just been given a book called Porsche, The Legend. (Jonathan Wood. 1997) It cost the grand sum of £1.00 from Tesco. It is an A4 sized (landscape format) all colour hardback with two sides on 34 Porsche marques from the 1948 356 to the 1994 version of the 911 (993) and Boxter. What is good to see in this book is a good showing of the water cooled cars in the form of separate coverage of each of the 924, 924 Turbo, 928, 928S4, 944, 944 Turbo, 944S2 and 968 marques. Nothing at all cerebral (unpretentious), but nice pictures, simple facts and a concise specification table for each. 

On a more serious note, I have just removed the original Blaupunkt Toronto SQR 46 from my car to replace it with a JVC MP3 CD unit. On removing the original unit all wiring seemed straightforward but for the fact that there was a white wire, looped through the radio, which becomes live when the unit is switched on. The information printed on the radio says that this wire should be connected to the 'Dashboard lamp (dimmer), if available'. The wire looks as though it was connected to something, as it has a long narrow (bare) metal terminal fixed to its end, of the type that usually is found holding a wire into a terminal block that forms the male fitment. The radio was very difficult to remove from the dash mounting and I assumed that I must have unknowingly ripped this wire from its connector block - normally this would be almost impossible to do because the metal terminal is usually keyed into the block. I can't find any terminal block with a wire missing and nothing close enough to the radio aperture (that is visible anyway) from where it could have been pulled. However, I cannot believe that the radio would have been fitted with a bare live wire hanging loose.  Can anyone offer advice as to where/what it might have been connected to please?

Many thanks,

Don.
