I have for sale a W124 E320 upper wiring harness.
THIS IS ONLY FOR "FACELIFT" 1994 and 1995 E320 MODELS ONLY.
Excellent condition, and a replacement harness that was manufactured in July, 2004. All connectors intact, wire wrapping and zip ties at 100%, and includes intake air temp sensor. This was off of a 1995 E320.
The harness also includes the integrated plastic tray, and the rubber piece that fits along the inside of the spark plug compartment atop the M104 engine.
THIS HARNESS IS NO LONGER AVAILABLE FROM MB.
MB list price was $1,490; discounted new is available for around $1,100-1,150.
Price is $200 including $25 shipping via US Priority Mail, anywhere in the US. That's $175 for the harness, plus shipping. That's VERY competitive with eBay harnesses, etc.
