Excursion in my sig. I kept the A/C compressor from the Dodge and spliced the Ford lines into it. I need some expertise on how to wire it up so it works with the A/C switch inside the Excursion. Help its getting hot outside.

 

If you will cut the dodge plug off the harness and splice in where your ford plug used to go to the compressor, it will cut the compressor on and off. Make sure to use the correct wires(measure for 12v). Thats how mine works on the common rail compressor. I also have a manual switch for the fan clutch.
