Thanks boys for the good help. You wouldn't believe the wrong advice I received from some sources who should know better. For example WRONG:"right side of wheel well under the body putty on floor of cargo space!!" WRONG... Also WRONG:"behind passenger side paneling" WRONG..I found the 6 pin white plastic receptacle behind Driver's side (left) side panel. I tested it with voltmeter first and it contains all the correct signals AND 13.2 Volts Battery lead. I bought a Hopkins "Hoppy" # 43855 Isolator unit and the wire labels are the same. Haven't put it on yet as I haven't yet found a path way through the floor to the underside of car. ADVANCE Auto parts got the hoppy in one day from their warehouse. Also, I had the hitch put on by U-Haul as my dealer advised that. He said they could do it better and used the same hitch as the dealer would. Ha-Ha LoL !! The instruction sheet with the U-Haul Hitch said plainly "Lower the Exhausts NOT THE MUFFLERS" (two mufflers) The black guy doing the job ignored that and it took him 2 1/2 Hours for a 30 minute job. Can't blame him for thinking so as it looks like a cinch to lower the mufflers but that won't work. So be forewarned, fore-armed.
