I do have the Parrot CK-3200 set-up using a wiring harness that i got from www.parrotkits.com (not affiliated with them). Even with their harness you will still need to hardwire the switched/ignition wire from their harness as it is not supplied from the harness coming the truck. I got the switched power source from the fuse box on the passenger side. I can't remember what number but i can find out if you need it.

Hope this help.
