Thanks Black Mercedes. Could you elaborate a little. I took a quick look at the engine compartment , but didn't see anything that I could readily identify as a wiring harness. Where is it in a 95 C280 with a 104 engine? Should I be able to tell if it's wearing out (frayed or something obvious)? Are there more than one?
Also the parts dept. didn't seem to recognize the part called 'wiring harness'. Does it go by any other name? Thanks for your help. Bob H
