I have an 03 6.2, is there any cross reference in the auto world for the Iac or do I have to get one from Mercury.

autozone AL25 or something like that. $25

Found some, pass along the info, these fit 01 to 03 Ford Windstar with 3.8 v6. Get two for the price of one from mercury.
Duralast from Autozone #TV278
Standard # AC423
Motorcraft # CX1766
BWD # 50558 Oreilly carries

Be sure to compare them carefully. I bought a ford iac, and found the connector was different and it was turned 180*. No way it could be used even with the right connector. I have 496 Mag HO's.

I did, have it installed already. Pictures of it in link.

Yup, I compared numbers, i had gotten a different one. I think the motorcraft # was 1768.

I havent had good luck grossing Merc part numbers but I have had some success with crossing Quick Sliver or Sierra part numbers. I usually start with Google and find the Merc number and work backwards towards NAPA. This holds true for many of the bolt on parts. Good luck.

It's a Delphi CV10103 made for a 2002 Ford Windstar. I bought just it Amazon Prime for $47.
