I wanted to give a quick update on my wiring harness/trailer hitch installation. I located the wiring harness- it's in the rear quarter panel on the driver's side just next to the 12v power outlet. I had to fish a little bit to pull it out, but it wasn't too bad. Installing the Curtis trailer hitch by myself is a whole different story. Probably the most difficult and physically demanding car repair job I have ever done- even worse than completely tearing apart and rebuilding my '79 Triumph Spitfire!
