Right after the dp before the cross member

 

There are you guys running the wires and switch?

 

I have my SP boost activated cutout installed after the crossmember, before the muffler. There was no space to fit it immediatly after the DP meets the horizontal exhaust pipe.

 

My cutout is just before the muffler right after the crossmember, it's a 2011 ccsb like yours. There is a body drain plug under the rear passengers floor mat area. I ran my switch inside my center console and ran the wiring down under the carpet under the passenger seat and out through that drain plug. Only leaves around 12" or so of wiring outside the cab excluding the pigtail off the qtp cutout. Very clean and easy.

 

Another pic of mine
