Does anyone know where, other than a dealer, I can find a main engine wiring harness for a 94 E320/320CE coupe with a 104. My local dealers are quoting me $1200.00 and up.

click on the "Fastlane" banner at the top of this page. Call and ask for Phil. he will ask for your VIN or possibly the part number of your current wiring harness.
regards,
Mark

phil has them for about 900 - 1000

Thanks. Anyone else ever have this problem??? I'm told there may have been a recall and either the dealership or Mercedes might cover the repair. The insulation on the entire engine harness is crumbling.

Do a search - you can read for a few days.
