Howdy all, I was told by the local Ford dealership that I need a cruise control amplifier module for my cruise to work. They gave me a part number and the service mgr seemed pretty adamant that the part I need is f37z-9d843-a. In my internet search I found on ebay the following, http://www.ebay.com/itm/250974982529...84.m1438.l2649. It says the amplifier they have will fit my 94 Ranger but the part number for it is F1VF-14A608-CD. I emailed him but have yet to receive a reply. Is there any major difference between the parts? Does anyone out there know the answer to my dilemma? Or does someone have or know where I can get the part f37z-9d843-a? Any help will be greatly appreciated.

I finally found the part (part #F37Z9D843A) at http://nosfordltd.com/ out of Texas. They only had one and now they have none. Hopefully that will solve my cruise control problems.

Got to part today. Right number on the box but the part inside is a different color and has an extra A at the end. I am not sure what vehicle it is for. Any ideas? Any help will be greatly appreciated.
