Mercedes Biodegradable Wiring Harness - W140 - M104

[@nkenchington6575]

Late 1991 - end of 1996 were the affected years. All models!

I have a 94 sl320 and the old harness has no tag how do u know what replacement harness u need

[@Koza_Cara]

Just look up sl320 wiring loom or wiring harness and you will find it on ebay

[@sligo7182]

Hi, what is number of the engine? M104xxx? I thing they were only affected from 104992 and later. Thanks

[@Nickword1]

Do you think taking the wire harness out of a 1994 S320 is the same process as this car since the engine is the same?

[@bolognablake]

I would imagine it's very similar. It's a super easy job

[@mercedeslove4291]

Delphi made most of the replacement harness

[@fieldlab4]

But what about the wiring throughout the rest of the car? Under the dash. Seat heaters. Airbags. You just hope for the best on that? Yikes.

[@nkenchington6575]

I believe that that wiring is good old fashioned normal plastic.

[@tommyspacs61]

Nope. All biodegradable crap. Have a 1992 600SEL that is subject to this also

@@tommyspacs61 damn I thought it was 93-96 only?

[@edvardsz3539]

@@tommyspacs61 no! I have a 1992 300SE. Only engine wiring harness is crap, other wiring on car is good, no bio shit.

​@@NadorFootage From 1993 W124. If you have a w124 from 1992.. no problems.

'Eco'... it was a bad idea to start with.

[@brabus8317]

I paid around $700 for mine harness

[@Koza_Cara]

That’s probably brand new

[@henrik1743]

that's an insane good price

[@dubpong]

@@henrik1743 kurth classics company in Germany makes these and ships them globally for that price. just bought mine for 700 including shipping to Finland. SUPER good job and now my mercedes runs as NEW
