I am aware that this question must have been answered a few thousand times, but i still don't get it:
Can i buy in ebay a whole instrument cluster from a w116 450se to use in my w116 280s?
Will the 8 cyl tacho work in my 6 cyl 110?
Thanks,
Claudio
I think the issue is that the tach runs off the coil input. Of course, a 6 cyl engine fires six time per revolution and so on. As MT stated in another post, the tach would need to be set up to account for this difference.
I have no idea how you would go about doing that, though, as I haven't looked at the circuits of these tachs in detail.

TJ's right. No idea how one can be converted but basically an 8cylinder tach counts every 8th pulse and a 6 cylinder tach, every 6th pulse.
Further to that, the gearing behind the speedo/odo will be different too I presume. I've compared a 280 and 350 speedo/odo and that was the case. So look for a 280 tacho and or a complete 280 instrument cluster.
