Has anyone else installed the SWI-PS unit on a 06 Explorer or 07 Edge? The instructions have me cutting the purple wire, attaching a resistor to one end, attaching it to the white wire and then to pin 18 then connecting another vehicle wire to the ground. Does all of this sound right?

yes, just follow the directions carefully. some cars are more involved than others, but they do work in the end

YEp works perfectly.

New SuperDuty is that way, too. Just follow each step as written, and you will do fine.

Thanks for the confirmations. I wish it was more idiot proof!

I appreciate all the help that I have received with my AVIC installation so please forgive some more questions:

1. I have followed the instructions for cutting the purple wire, soldering a resistor to one end and then the other end of the resistor to the white wire. It says to connect the white wire from the SWC to pin 18 in the car. Where is this "connector" under the dash? It must have something to do with the wires from the steering wheel. Does this mean I need to attach the white wire to a wire that goes into pin 18?

2. The instructions then say to "connect pin 19 blue/white wire to ground. Do I attach a ground wire from the AVIC harness to this wire?

3. Can I cut off the majority of the wires that I am not using (close to the plug) to get rid of the excess and save some room behind the dash?

Thanks in advance for the help.
