The oil pressure gauge on my 1995 E420 flickers wildly and the oil level light stays on. My mechanic says I need to replace the starter/alternator wiring harness (connects to the starter, alternator, and oil pressure, and oil level sensors) because the insulation has degraded. I have been trying to find the harness for months with no luck. Does anyone know where I can find this harness?
I saw a posting by someone who was replacing the same harness on a 1994 E420 but he did not say specifically where he obtained the replacement harness.
