I just bought my 72 280SEL 4.5. It had suffered an engine fire years ago. Ran VERY rough when I purchased is. I built a new wire harness complete with new connectors, double heat shrinked connections, and protective loom for about $200.00 ($120 for connectors, $30 for loom and $65 for wire and heatshrink) The car runs great now. It is not that dificult. I removed the entire harness, put it on the bench and replicated it wire for wire. Make sure you buy wire rated for under hood applications, the stuff at auto stores is not. (I bought GLX cross link in several colors)

Sweet! I did that too, but I boned up a couple of the wires - it made the car run even worse I'm not sure I spent enough time and care in making it right
