HIi
SO i have a OM606 non turbo in my w126 which started life as a 560. It still have the original rev counter which red lines at 6500. I have found a diesel rev counter here in a junk yard but my electrician has indicated to me that there are other missing bits i need. Is there anyone on the forum who can show me with a pic or a link all of what i need to get my dash to have a working tachomeer.

I think he said it was missing a sensor and a cable, but there were language issues.
thanks for your help
