1993 lincoln town car

The engine has it's own harness, just google "engine harness" for your year, make, and model. It has to be exactly right, even minor changes between years can make a harness incompatible. You're going to need a wiring schematic from a manual. Don't rely on internet pictures, get a manual. You can buy a print book or subscribe to either Haynes or Chiltons, the subscriptions have the added bonus of more photos in their write-ups. You can *try* and patch a harness back together, but that is not an easy task. If you can't source a factory replacement harness, you may want to look for a parts car or salvage yard harness, but that's a tall order as well.
