Hello, I have been getting some inaccurate advice from my local MB indy. My car 1993 300E 2.8, swapped a 3.2 with less miles from a '94 E320. My wiring harness was toast, I bought a harness (supposedly correct) from the indy. However it was not the correct one, the part number is 124 543 20 06, for sale now in classifieds. So, I bought another harness, used replacement from a different '94 E320 than the engine donor. Are there any compatability issues using the '94 3.2 harness with my '93 2.8 ECU? All of the connectors matched up and were the same. Any guidance is greatly appreciated, this site is where I will be getting repair advice from this point on.
