I ran a wire from the interior light circuit thru each door harness/grommet up to the mirror harness
the puddle light wire is orange/black which is found on the harness going from the door switch to the mirror, so you have to take the door panels off to get to it
you only have to run a single wire to each mirror, the ground is constant already. If i remember correctly there are 2 orange/black wires on the mirror harness and the one you want to use is the one in the middle of the harness connector the other one is on a outside edge corner.
