Needed urgently to complete work on my truck. The 4wd motor will not apply the reverse voltage so that it returns to 2wd. I need the wiring diagram to know where I can find the relay to check that, HEEELLPPPP!!!!

 

You need a new motor. There are contacts in the motor that go bad. You may try taking it apart and sanding them clean.

 

I don't know if this will help but the Sevice Manual states it is located behind the Center of the Instrument Panel.

Though it looks more like it's in the center of the dash from the Component Location View. (See Link) https://www.f150online.com/galleries...060-107154.jpg

Here is a link to the connectors that may help you too. https://www.f150online.com/galleries...060-107155.jpg

 

Thanks a million, will check that out Ddan

 

DDan is it possible for you to scan that image any larger, when I print it I can't seem to read the text.

 

I scaned if full size. For some reason when I upload it to the Gallerys here it shrinks it down.

If you send me a message with your email, thru the link on my profile here or thru Yahoo Messenger. User ID DDan1967

I can send it to you full size

PS Just some additional info. From the image it looks like the relay is under the access panel in the top of the dash. (the depression that seems to serve no perpose)
