Ok I have a stupid question but I was wondering if.

Would a ford rangers wiring harness(interior) be the same if it had power windows or roll up windows.
I was told that ford like other manufactures have one harness for both. They just don't use the wire connection if it has roll down windows and its not hooked up to the fuse block.
I just bought a ranger that needs a door replacement, it has roll down windows now. I figured that if the wire is there I can replace it with an electric window door.
I know it sounds dumb and I have my doubts but I figure I would get opinions from others that may know. my email address is bullelk22@hotmail.com
Thanks Tony
