well thanks to firstdown80 and part# A 156-540-01-06 that he found i've made some progress.
it looks like that harness if swapped with the factory installed harness will add the auto dim mirror.
the red circles in the attached pictures show the 2 mirror connectors, the white for the led map lights and the missing blue for auto dim,compass and homelink.
so now a new a problem of trying to figure out how to swap them.
it looks like the harness connects to another somewhere down the right side "A" pillar?
Good to see these pictures. Does homelink work as well?
Are the other connector ends of the blue and white wire connected to the overhead console? If so, see if you can unwrap the wires from the black protective wrap and remove the other wires. Rewrap it and tuck it overhead.
