Pin out for the transmission wiring harness needed?

Hi,

I need to confirm the model years. Is the truck a 2000? What year was the expedition? What harness was cut? Was the "extra harness" for the same sensor and only the connector was different or is it something your truck simply doesn't have?

Let me know.

Hi,

It is possible that you may need it. That leads to a different concern, engine controls. They make nothing easy anymore.

What year was the Expedition?

Hi,

I went through the wiring schematics. In 2003, the Expedition had one engine option, a 4R70W. The wiring schematic is two pages long for this vehicle. However, I had to cut each pic in half to make them readable. Therefore, the first 4 pics below are from the Expedition.

Pic 5 is related to the 2000 F150. There were two different possible transmissions. One is a 4R70W and the other is a 4R100. I'm not sure what your truck had originally. Here is another concern. The wiring schematic for a 2000 F150 with the 4R70W is only one page. Therefore, something is different. Pics 6 and 7 are the wiring schematic for the 2000 F150 4R70W. The last two pictures are of the 2000 F150 4R100 transmission.

At this point, I would start by determining the OEM transmission model your truck came from and then start trying to match wiring colors for confirmation. Then, determine which connector was cut from the Expedition, and locate the wire colors on the schematic to determine what you cut and if it exists on the truck's harness.

Also, if you still have the transmission you removed from the truck, lay it side by side with the replacement and compare connectors.

Let me know.

See pics below.

Hi,

I'm not sure how you spliced it. As far as the harness is concerned, this is untested territory. I can't guarantee it will work. But yes, I would be using the harness from the expedition and the module.
