I ordered all my install stuff from crutchfield. the harnesses that you can buy from the mart or big box stores does not come with the additional adaptor. good luck
1) Metra 71-048 Speaker Wiring Adapters Work with select 1998-up vehicles — connect new speakers to the factory wiring plugs at Crutchfield.com

2)Receiver Wire Harness For select 2003-up Ford, Lincoln, Mazda, and Mercury vehicles at Crutchfield.com

I'm assuming #2 is the harness you're referring to
