Also, the W123 has a physical oil pressure gauge with an oil pressure line running into the dash, while the W126 has an electronic sensor for oil pressure.

So looks like its time to swap glowplug harnesses huh? Also, my 300D engine does have a magnetic pickup sensor on the bellcrank, why does it have one against the flexplate? When I removed the engine in the 300D I had to disconnect the white wire running to the rpm sensor at the bellcrank, It was plugged into the bottom of what looked like the tach amp on the drivers fenderwell.
