I have just acquired a radio from a 75 Shadow And want it installed into my 74 Shadow. Anyone in Queensland with knowledge of how to do this or knows someone who can. I'm useless with anything electronic Thanks Kevin | |||||

Kevin, I have re-installed mine in SRH20280 (which is also a 1974 Shadow) Unless you also have the 8-track installed it should be a fairly straightforward installation. Any auto-electrician who does sound system installs will know what to do. However: is the radio going in between the front seats or at the top of the centre console triangle? And do you have another (modern) headunit installed in the car? The reason I ask is that there are a few screws behind the sides of the centre console woodwork that make installation a bit easier - if you don't know about them the installer can tear the trim getting the radio and/or headunit into place. The one cardinal rule is never switch on a radio that isn't connected to the speakers. I have a collection of original Blaupunkt technical diagrams and instruction booklets I could scan if your local guy runs into anything unfamiliar. I have mine running through a 'line-feed reducer' as an auxiliary input to the modern headunit in the console. | |||||

Jeffrey I have the 8 track but it's never used, just there for show. The Blaupunkt will go in front of the ashtray between the two front seats I don't want an up to date system in the car as I have a separate unit that takes the IPod and is sufficient for our purposes. I'll let you know if we run into any issues and thanks for the offer of scanning some booklets. Kevin | |||||

That's good; not using the 8-track means you can get the radio wired direct to the speakers - saves a lot of hassle with the relay system for switching between devices. This relay is located in the centre console screwed to the inside of the passenger side footwell black trim triangle - where you'll also find the speaker wires. The wiring diagrams show which colours go to which door speaker so your installer doesn't have to remove the doors to check. http://rrtechnical.info/sy/tsd2476/15.pdf Page 56, bottom right hand corner. Front Right +ve is Slate/Purple SPP " Left +ve is Slate/Brown SNP Rear Right +ve is Slate/White SWP " Left +ve is Slate/Yellow SYP Each speaker has a SBP (Slate/Black Plastic) negative return wire. The installer will do a continiuity test to match each one one up with its positive partner. The radio only has 2 outlets so there'll be a splitter/joiner inserted in there somewhere - and you'll get basic balance control between front and rear speakers through the dashboard knob. For future reference as well - if anybody is looking for knobs, faceplates etc for these and other German radios there is a lovely couple in Munich who specialise in repair & remanufacture of these period radios which were the radio of choice for Porsche and VW over several decades: CARS - Classic Auto Radio Station http://www.oldtimerradio.de/shop/index.php | |||||

Jeffrey since you have been generous with your information, attached are three pics of the item in question. There seems to be a lot of additional wiring where the current unit sits as the current installation is not a Blaupunkt Kevin

Kevin - That is the Blaupunkt model which was used in European delivery Shadows. The L M U buttons stand for (I think) our AM, FM and possibly shortwave? The US delivery model had shortwave. All the radios were high spec variations of the "Frankfurt" model In any case the Australian delivery Frankfurt radios had 3 AM buttons and 2 FM ones. It's possible your radio would pick up Australian FM stations but I can't be sure (the bandwidth is roughly the same) Here is a picture of the Australian delivery radio from SRH20280 - the buttons are replacements without the AM/FM decals and the wood surround is for a European radio (mine went missing in the post to the re-finishers!) hence the centre cutout is different - in fact it is the same as yours. The US cutout has a different spindle hole centre width as well.  You might be able to source one from the man in Brisbane who dismantles old Shadows - Ken Balmforth (07)38564911. Unless however it comes with it's own wood surround you might find it difficult to get hold of an Australian spec cutout; I'm going to have to get one made eventually. In the meantime I've ordered a metal bezel which will adapt the surround to fit (I hope)  The extra wiring you mention could be aftermarket but there is of course also a power, negative and aerial cable under there as well. | |||||

Im actually seeing Ken tomorrow for a couple of other things. I got this radio from him, it came out of a Shadow. Given the original wiring underneath, how would one "wire" it up I have checked the size etc and the Radio does fit nicely in the space and the Walnut is as good as it gets to the finish on the rest of the car.

The actual wiring is fairly straightforward once you've got the speakers sorted: The 2 speaker plugs go where the purple arrows are (they are little 2-pin plugs) The power goes to the red arrow The white arrow is the automatic antenna connection which isn't used The 2 blue arrows are earth - the centre one with the nut uses an earth strap direct to the earth point under the ashtray and the lucar type connector is a spare (e.g. if you want to earth a splitter etc) The yellow arrow is the antenna connection.  | |||||

Thanks so much, I will be trying this tomorrow Kevin | |||||
| Jeffrey McCarthy Grand Master Username: jefmac2003 Post Number: 382 Registered: 5-2007 |
Kevin - hopefully the 2 little speaker wire plugs are still there - they are about 1.2cm x 1cm from memory. If they aren't you could try one of those radio repair shops. Or even Ken might have some lying around. It's even possible that the 8-track wiring still works - stranger things have happened. 8-track tapes are still available on ebay (I hope you like Elvis...) Each plug has a +ve and a -ve pin so an auto sound type person should be able to whip up a couple of connectors in any case. Good luck | |||||

Quite frankly I just can't see this need to keep everything as it originally rolled out of the factory gates. The ethos of Messrs. Rolls and Royce was to make the best possible car using the best proven technology available at the time of manufacture. Don't you think that our Shadows would have been fitted with CD / USB / Bluetooth / SatNav / etc. if it had been available at the time? Why else (apart from errors in component design) were the specs of the Shadow 1 quietly upgraded time and again during its lifetime? Does anyone balk at repainting in 2-pack epoxy which wasn't around back in the 60's & 70's? Admittedly I would shudder at the thought of having to replace that mighty V8 with something more mundane - although much cheaper - if mine gave up the ghost (pun intended). But if that was my only financially available option ... Have you seen just how fanatical the concours judges are about panel alignment at Jaguar 110/120 meets? Why? The damn things were being rushed out of the factory at such a rate to satisfy American demand that there was no time for quality control to that kind of level. As such the panel fit was more like hand in shoe than hand in glove! "Is it in place?" "Yes." "Will it fall off?" "Not today." "Good enough. Ship it out!" | |||||

Jan it's not so much a matter of meeting some councours judge's idea of authenticity as an appreciation in and of itself of vintage radio technology - you're either into it or not. I for example have a top spec modern pioneer headunit with all the hidden bells and whistles and have spent many many hours integrating it seamlessly into the Shadow console. Anything to avoid the unsympathetic dog's breakfast install that's been inflicted on too many of the cars. The Blaupunkt radio is of an age with the car, looks like it belongs there and has the bonus that I can tune it with one hand and my ear instead of going through a mind-bending sequence of button pushing when "the computer says no". Modern sound systems have become small enough to have the best of both worlds - and that I think is a good thing, no? | |||||

A call for a little bit of help with some odd wiring notation. In the process of tracking down the wiring diagrams for the 8-track plus radio set-up in late series one cars (1974? onwards) I've come across some wire labels I've not seen before. Naturally the diagrams appear in later serial number diagrams than they do on the actual cars. They also handily split over 4 different scans in the library. These things are sent to try us! I've scanned and printed and glued etc and have a full diagram of the whole setup should anyone ever require a copy but for now if anyone knows what the following mean on the below diagram?: 9SB 9SO 95K I have a suspicion that there's one each positive for each radio speaker connection and a common earth. If so does the common earth split to each connector or just connect to the lucar tab on the back of the radio? The diagram seems to indicate the latter.  The 3 wires in situ i.e. hiding under the ashtray on the actual car are: Slate and Black Slate and Green Slate and Blue | |||||

This is a shrunken version of the whole circuit diagram I cut and pasted (It's on its side because of the 640x480 limit; the site only accepts landscape not portrait)  | |||||
| Jeffrey McCarthy Grand Master Username: jefmac2003 Post Number: 392 Registered: 5-2007 |
It would also be useful if someone knows what the 14R just below and to the right of the word 'RELAY' on the above diagrams refers to. 9SO and 95K obviously go from the speaker connections in the back of the radio to the balance control and 95B is the common earth with the speakers. If anyone wants to look at the diagrams directly for clarity they are here (on page 127 of the scanned pictures) under: Rolls-Royce Corniche Saloon and Bentley Corniche Saloon ALL CARS FROM SERIAL NUMBER 22583 http://rrtechnical.info/sy/tsd2476/16.pdf | |||||

Hi Jeff, The numbers and letter sequences you refer to are the insulation colours and number of strands of the various wires as follows- 9SB = 9 strand slate with a black tracer 9SO = 9 strand slate with an orange tracer 9SK = 9 strand slate with a pink tracer 14R (if it is an R as it is a bit unclear) = 14 strand red Hope this helps, KInd regards, Chris | |||||
| Jeffrey McCarthy Grand Master Username: jefmac2003 Post Number: 393 Registered: 5-2007 |
That actually does help a lot Chris. Orange and Pink tracers don't appear anywhere else on the earlier Shadow diagrams that I know of. I'll have a hunt around for a later colour code list. I suspect that in this case of a couple of production cars about 2000 serial numbers before the set-up appears in the diagrams that some of the colours may have been slightly different. Also for future reference the diagram above is for non US and Canadian cars. For the slightly different norte americano arrangment go to this thread. http://au.rrforums.net/forum/messages/17001/13399.html | |||||

Poring further over the diagrams it is possible to see the development of the system. The dual system appears in the Corniche from circa 1973 onwards but with a mono radio/stereo tape set-up. The Orange/Pink (or whatever) tracer wires were referred to as "radio flying leads" and were denoted by a + sign without any further indication of colour or size. Kevin and I have been working on this behind the scenes so I'll report back on our progress. |
