For some reason I thought I read soewhere that 94 and 95 E320's had two plugs per cylinder. Is this true?

No, that came later on the 112 motor in 1998 E320.

The confusion prob comes from this system having a coil for 2 plugs.. meaning a "Waste Spark" ignition system, where the coil [ 3 of them] fires two cylinder at the same time, where only one is on compression stroke, so the other is a wasted spark.
So , this system [ and your chassis ] has 3 coils and 6 plugs.

Thanks very much for the clarification and education...

Tonight I'm tackling the replacement of my engine harness. Picked up the part today at my dealer and am trying to keep the cost down by replacing it myself. Any cautions or guidance is most welcome. I did look over the post on this forum regarding "wiringing harness replacement". I don't have it in front of me or I would acknkwledge the author and express my thanks. I'm off to the garage right now to get this chore underway.

A worthy tip for you..
On 104 HFM engines , also change the plug connectors under the 3 coils and use only Bosch F8DC4 Super Copper plugs

Thanks for the tip...

I finished the removal and replacement of the engine harness a few minutes ago. In consideration of your tip, I'm didn't close-up the engine cover, I'll go to the dealer in the morning and purcahse the connectors and plugs as you suggest. Thanks again...

Arthur, do you mean I should change ONLY the three connectors under the coils? Should I also repace the wiring/connectors to the other three plugs as well, or leave alone?
