About 6 months ago I drug out of the weeds an 07 Outlander. A neighbor had just parked it when it quit running. I have put a lot of time and $ in it. Rebuilt engine, etc. Got it running but the speedometer does not work and no display (does light up). Found one off an 08 and would like to install. I read somewhere that it should work, need to change some wires around? Will I have to have it reprogrammed? Any help would be appreciated.
