Thanks. I called and they were very helpful with information that the harness is there, the color of wires including what each one does. Now I just have to find it.

I have a 2007 National Pacifica and wish to add a electric brake modulator for the trailer I pull. Thus far I cannot identify the proper wires under the dash to connect to. I have a 7 pin plug on the coach and am good with electric issues. There is a harness not connected to anything under the dash but no "blue" wire so it just doesn't look right. Any ideas? Prefer to do it myself. Thanks, Jerry
