By chance I came across this ribbon cable! Wunderbar! So short measured the exact length and simply appointed times.
The cable supplied is quite flexible and thus adapts to almost every corner of. Something hot glue to boot and it may lsogehen.
So just unscrewed all baseboards and placed the cable behind it. Then the bodies were where it was tight! Door frames and door edgings. But no problem, the cable is so thin / flat that it fits wonderfully topsy ago, without generating a large Knubbel.
The connectors are pressed neatly and the ends of the wires (as far as I can see) in perfect order.
Sometimes the old tried and tested cable connection is just but the best!
