I finished up the overhead 3 guage setup this weekend and had a bit of a tough time figuring where to feed thru the firewall on my 06 2500, well after looking at it a bit I noticed a simple block off plate for the clutch master cyl. at the pedal cluster, well I removed it and drilled a 7/8 " hole installed a goroumet and bolted it back to the firewall (2 nuts inside) and ran the wires thru neatly. this tip will only work for the auto trans guys.

Yep thats where I ran mine too, you can always buy a new plate if you need to put it back completely stock.
