Thanks for your comments.

The cable was hanging to the left of the transmission and severed. The other end was disconnected and jammed up underneath the dash. I don't know what the terminal looks like on the transmission itself. Anyone have a photo of either type as it connects to the transmission?

Can anyone confirm that the white-bowl-with-metal-rod setup on the back of the speedo is the electronic version? I also have a mechanical speedo from my 76 450 SL parts car. I assume that the (mechanical) speed sender from the transmission would be somewhat different from the electronic sender?

My wheels and tires are factory...the speed readout is almost 50% greater than actual speed. Would larger wheels diameter make the readout lower than actual speed rather than higher? The odometer seems to match the Carfax so it is probably OK.

ljmauricio, do you need photos with the bumpers off or with them on (photo from underneath)? My bumpers will be coming off again but not for a few months. If you could use photos from underneath, I can get them for you.
