The wiring in the fuse box was revised during the 2003 model year...although the factory tow-trailer harness instructions show a connection from the harness to a red wire in the fuse box,the wire I needed to connect to is now a red-white wire.
S,note to self,if doing any electrical on the car check to see if the wiring has been revised at any point during the model year.
Thanks to those who provided advice
