I have a used ProEFI 128 Plug and Play harness for an E46 S54 M3. I bought it off eBay with a ProEFI ECU I'll be using on my E36, so I don't need the PnP harness. I have looked it over carefully and I don't see any cut wires and loose ends. $450 obo without ignitors for stock coils; $600 with two 3 channel ProEFI ignitors ($169.56 each new).

PM me if interested.
