The mirror harness wiring solved the problem.
Thought I would share the final result in case any parts of it provide needed information. I ended up going with the "Mirror Tap" ordered directly from Blendmount. As I have an Escort 9500ix, I went with the visor clip mount from Escort (ordered via Amazon).
I went with the 20" Mirror Tap (longest currently available) with Micro .05 connectors. Tapping into the mirror harness was easy via the information quoted above from russ71 and they fit perfect. Mirror Door closes without bending anything and there is room for the new cable to come out of the mirror door next to the existing mirror cable.
From the harness I ran the cable up to the top of the mirror clam shell casing where there is a couple of existing cables slightly exposed from the gap to the headliner. I secured the Mirror Tap cable to one of the existing exposed cables with a small cable tie which was included with the Mirror Tap purchase. Secure the two only "snug" so there is still some play with moving the Mirror Tap cable as necessary.
The best part about this approach is how nicely the Mirror Tap cable will tuck into the overhead console edge with minimal effort. As you can see from the photos, I made the cable go in straight as possible from the mirror casing to the overhead console edge and come out as near to the 9500ix as possible for a cleaner look. The cable will also sit up on top of the visor when not connected to your detector so it doesn't just hang down randomly.
Overall, I'm satisfied with this method of install. It could certainly be used with any suction cup or other window based mount. For me, it is certainly more convenient than the dash mount bean bag I had been using. I liked it but with the extreme heat and cold throughout the year the velcro on the bean bag and detector was melting and moving on me. And I've avoided suction cups which I personally haven't had much success with and I don't like to leave suction cups (or suction cup rings) on the windows for prying eyes. For those with the 9500ix, being underneath the visor (and therefore roof) has had no noticeable effect on GPS reception as of yet.
of this solution:
1. The maximum length of the Mirror Tap cable from Blendmount is 20". This does not allow mounting my 9500ix (or likely anything else) on the driver side visor. So my detector is mounted on my passenger visor (and by viewing my pictures of this style mount I used every bit of the 20" cable to get even there). I would have liked a longer cable to not only mount to the driver side visor, but possibly run the cable itself in the mirror clamshell housing as well (though I don't find it intrusive not being in there).
2. Doing a visor mount on the W2k will not be level and will point downwards. You have to put something between the visor and headliner to level it off. I used one of the small inflated plastic bags that Amazon often uses to pack items which is perfect sized. I'm sure someone more ingenuitous could find a better method/prop, but since it is on the passenger side visor it doesn't distract me at this point.
Hope this helps someone!
