The best wire harness use is from a 98-99 Monte Carlo or Lumina with a N/A 3800. If you get one of those it should only require swapping a few wires in the large C100 connector on the firewall, it's not worth paying someone to do it for you. Other wire harnesses will work but require a lot more modification. The ideal engine/trans donor car for you will be a 98-04 Regal GS or 98-03 Grand Prix GTP. These are the only two that will have all of the brackets and mounts you need. Tons of other cars have L67s but will not be a direct bolt in without first swapping parts from a w-body 3800. There are a number of threads on the swap on other forums, they are not specific to the Cutlass but all of the same stuff still applies.
