Wompa 0 Posted April 28, 2019 Hello everybody! Is there someone that has experience with Blaupunkts 90stereo. Im trying to do a correct harness for the stereo and where do I start. I need the big ISO connection for the head unit but what is that for. And how do I connect the amp. Via the din connection or. And I also have a CD changer... where and how does that connect. Is there a blaupunkt harness with all the connections that can be bought or do I need to make my own. I need some guidance to make this as original as possible and working.

Philly-R6 0 Posted April 29, 2019 (edited) This any help to you? It's the FRANKFURT RCM 104, though... https://www.blaupunkt.com/fileadmin/user_upload/Service/SERVICEDOKU_ZIEL/EA/GB/7644440510001_EA_GB.pdf ...or in English! https://www.blaupunkt.com/fileadmin/user_upload/Service/SERVICEDOKU_ZIEL/EA/GB/7644440510001_EA_GB.pdf Edited April 29, 2019 by Philly-R6 Quote Share this post Link to post Share on other sites
fendervg 30 Posted April 30, 2019 What wiring is present in your car - if you original loom is there you will have a brown and black rectangular connector and these should plug straight in - one is for the speakers and the other for power, lights etc. The CD changer will be a red ISO connector, but the changer will also need separate earth and power. I'll see what I can find, I should have a few radio wiring diagrams in the archives. Quote Share this post Link to post Share on other sites
Wompa 0 Posted May 1, 2019 I had the old Aktiv system but that is long gone for a amateur made harness with just speakers and power. The red ISO 10 pin is quite hard to just buy here in Sweden... But it seems that I need to create my own harness. And what I can see is that Blaupunkt used a DIN connections for the amp and is that just taken from the ISO speaker plug. So its just getting speaker input. Quote Share this post Link to post Share on other sites

fendervg 30 Posted May 1, 2019 That looks weird - try this. It's for the Gamma, but it should give you some idea, especially of the loom to the radio and colours, which will be essentially similar. I might have some more as well - will keep looking. stromlaufplan_gamma4.pdf Quote Share this post Link to post Share on other sites
fendervg 30 Posted May 2, 2019 Some more. The Aktiv system would have had powered speakers, with no amplifier end stage in the head unit - so you might find that there are spare power and earth wires for each set of speakers that will not be present in other cars.
