John, I am a little confused, are you talking about you had to cut behind where I have my rocker switches mounted, or did you have to cut behind where my monitor screen is mounted?
If you are talking about behing my rocker switches, there is nothing behind there on my jeep. Its a big hole and I had plenty of room for my wiring if memory serves me.
If you are talking about behind my screen, yes, I had to cut into the plastic, and then I realized it was part of the duct work. I had to form a replacement panel out of flashing material, and I screwed it to the outer edges of the plastic and used silicone to seal it all up. I had to be careful not to go too deep because of the vacuum actuated door/flap that controls the flow of air. Luckily my screen is only protruding behind the panel about 1/2 of an inch, so I didnt need to cut too much.
Let me know if we are on the same page?
