I chose to mount it under the shelf that has the ADAHARS and remote radio (par100ex) on it. A bit of a pain, but it's hidden and the harness is long enough to reach from there. I chose to put the switch where the flap motor body would trigger it in full up position. That's wired to the normally closed terminal of AFS's switch. Certainly not the prettiest bracket ever built..but it will work fine.
