1996 and up engine wiring harness

Based upon what I learned and posted about a few months ago, I think a small number of the wires (the larger ones) in my 96 harness had the old insulation on them.

I have heard that all throttle bodies have messed up wires.

MB stopped usage of the bio-degradable wiring on the engine harness on 11/95.
That 11/95 is the production date of the HARNESS not the cars production date. So some W210 cars had that type wire on the engine harness.

Seen plenty of them (1996 year models) including diesel & gas models!
The 1996 E320 does have a HFM fuel system. So did the 1996 C220, SL320, S320, & C280.

That was my point - that it's HFMs that fail in 1996, not MEs. In other words the problem seems to have gone away on V8s and V12s with the end of model year 1995 transition from LH to ME. I have 96 ME engine number 17xx and the original harness is fine, other than being plagued with unraveling friction tape. Also ME in 96 did away with the ETA harness and the lower harness (ground strap only) - so it's just one big harness that does everything engine. It's also a way more expensive part than the LH harnesses so it better not fail.
