Thanks for the Legend ( Instrument Cluster 15 pin wiring guide ) it worked perfect so indeed It's for a 1975 MB 450 . Newer ones I tried are wired different , Same color wire's but positioned different .
I made a jump Harness to swap the wire's but thanks to you did not need it as your legend was correct .
Read a few of your posts and your sharp on the Mercedes for sure . I can tell that immediately because I am a Mechanic of long standing . But on the Mercedes your a expert .
Thanks so much I am lucky you had the old book or access.
Regards Conrad
