Generation IV External Engine - Neat E-Cutout idea

Just got a set of kooks long tubes and i'm having a custom Y and merge made so i decided to get a e-cutout too. I was thinking of a place to hide the toggle or button to operate the cutout and decided since i dont use the steering wheel controls, im going to make it work with my radio volume button. Volume up will open it and volume down will close it. Im not sure if anyone else has done this yet or not, but i thought it was a neat idea. If enough ppl request a write up, i will do one.

I thought about that for everything from electric cut outs to nitrous lol. Write up would be interesting
