I found a deal on an overhead concole out of a Lariat that displays gas mileage. I want to know if it will directly swap out with my current display, or if another wire would have to be run for the milage function. Mine current consule has Temp, Compass, Domelight and Moonroof controls - '03 Supercrew XLT

Has anyone done this swap or know about the wiring?

Thanks

 

I'm also interested in doing this swap (upgrade) to have the fuel economy indicator. I have a 2003 FX4.

Anybody ever done it?
