good info. i would love to retrofit comand 2.0 to my 124 but dont want to spoil the origionality or damage the dash area. i reckon it could be done though and this is where you'd get the speed pulse
There's a 2-pin plug in late W124s with (from memory) thin black wires with a blue trace. I have a sneaking suspicion that is speed pulse as well. I'll have a look & report back
There's nothing to stop you butchering the console to fit COMAND but a taxi console would make life a lot easier
The green with white trace is the wire i attached, the factory wire is the one in the black trunking.
When i was inquiring on locations for the speed pulse Green yellow was mentioned but in the drivers side kick well.
Also Alpine themselves told me i need a speed pulse generator £180
If your car has cruise or abs you have a speed pulse signal at the clocks.
