Stage1 Mth/water injectionnstall install on my w222
i recently purchased a snow stage 1 meth injection kit for my 15 benz s550 with the m278 motor (biturbo 4.7 v8) . I have a question in regards to the install. I am about 95% complete but I am stuck at and with the boost switch. I can not find the location or hose for the boost pressure hose I am supposed to connect the t fitting to my boost switch. I looked and researched for days on where it is and can not find it. i have it currently connected to some vacuum lines and my pump wont engage. can anyone please help me on this matter or send me in the right direction. Thanks
