1995 S320 Engine Wire Harness

Hello,
Any solutions to a corroded, damaged engine wire harness on the 6 cylinder MB 1995 engine? Has there been any recalls or recourse against Mercedes for
this defective item.
Dealer is quoting $1200 plus tax to replace in Tyler TX and was hoping somebody might have another source/solution.
Also, engine error codes for #2 coil, both oxy sensors, ect sensor? all coming up at once. Is this common and should I replace the wire harness first to see if it's causing the engine error codes.
Thanks for any help.
Gregg

Many cars this age and older had defective wiring harnesses on their engines - heat kills the insulation (that was intended to be more ecological), the wires touch and short out. It's a mess but you have no choice but to fix it for you can't sell the car with it this way, nobody will buy it.
Wiring harnesses are some parts and lots of labor. You CAN do the labor if you VERY VERY carefully sketch where the old wires run and their connections. Some lay the new harness on the old one and slowly and carefully substitute new for old paying attention to the routing before making connections.
