you really don't need to remove the wifi board completely, just pop off the cable with a plastic tool or a small flat head even. Getting the cable back under slot one is tricky, and I repair these for a living. Straighten out the cable out first, there are two clear paths back to the other side, parallel to the 2 little twin fuses just at the 7 o'clock of the EM10, and another just above the EM10 itself, again running parallel.
