Title: Available MAIN HARNESS for W109-300SEL-6.3 much desired car 6,500 ever produced
Post by: lpeterssen on September 15, 2025, 11:16:11
Dear Friends

On an old, terrible shape wiring harnesses lot, (bought on ebay) I found another treasure.   As they always say: trash for some people is the gold's others.

Among all this chopped harnesses, there was one that after contrasting many times the wiring diagrams some things gave me the clue it was from a 300SEL-6.3.

So this fantastic Sherlock Holmes experience, which I enjoyed so much, ended with the production of a MINT MAIN WIRING HARNESS for a W109-6.3 (300SEL). It took me about two full weeks to finish this harness.

Almost all the lines, more than 95% had to be changed because were either missing, chopped or had a splice.

As you know, my refurbished harnesses are made with ultra care, and there are not EVER any spliced lines, because that sooner or later will cause problems.

Enjoy the pictures attached and feel free to make any questions.

This is a LHD, AUTOMATIC transmission , US-spec car.  With side marker signals.

The harness is published on my website here:
