Finding a place for the controller where it will be easily accessible, yet not in the way, is a bit of a challenge. I chose the Hopkins InSight Flex Mount for that reason.
The main unit is mounted out of the way, and out of sight, up on the wall just above and in front of the emergency brake pedal.
The hand control is just to the left of the steering column, on the dash. Easy to reach while driving, but not in any danger of getting hit by a knee.
The info screen is on top of the steering column, just below the dash instruments. Easy to see, without really taking your eyes off the road much.
You don't even notice the modules when you are in the car. All wires passed easily through the gap for the steering column - no drilling or cutting required.
Clean install!
Now, I'll try to add the photos! (I can't seem to get it to accept multiple photos?!)
