That wire is on the 84SD. I didn't pay attention because it didn't need to come out. You may be able to start the bolt form underneath then tighten with swivel & extension from above.

My '84 300D has the style that mach4 pictured. My '82 'SD doesn't have the wire that yours does.

That's odd. I have a 1982 300SD parts car as well (actually had two of them). The one I have now, I don't see the wire either. No telling what kind of can of worms I've opened. Like you mentioned, the picture from mach4 looks like the one that came out of my SD originally too. I just need get out there and look at it closer tomorrow and see what I can find out.
Thanks,

If you don't have that setup, it's a pretty easy task to pull the tach signal off the harmonic balancer and use the tach amp on the fender well. Unfortunately you'll need the correct tach module in the cluster too as the harmonic balancer sensor gets one signal per revolution while the flywheel sensor gets about 50 signals per revolution. The 84-85 tach get's its signal through the EGR controller - at least that's the way it's wired. An important piece of new information is that you can bypass the EGR controller and hook the VR sensor wires directly to the tach module in the cluster! This is one less piece of crap that is needed to adapt the later tach system to an earlier vehicle. Quote:

Tach
Cool. It's not the biggest of my problems right now, so I'll figure out the tach later. Right now I need to get the speedometer sending unit or whatever it is, in the back of the transmission replaced, and even more importantly, try to figure out why I can't get the cooling right. Runs great with the overflow cap loose, but starts getting hot when the cap is tightened downed (system pressurized I suppose). This has been a long frustrating process.
mach4, Love the info on your 380SL. I'll look it over in more detail after while. I've read about a third of the post so far, and I'm really impressed. Where in NC are planning to head to? I live about in the middle of the state, outside of Greensboro. Thanks much,
