help with new nitrous works wet shot

[tinas90lx]

i just bought the 50-175 adj nitrous works wet shot &purge kit (#13005) and i'm just not getting it. Right now my brain feels like space ace conjuction misfunction and cant seem to find the right answers (even though they r there). 1: where should I mount the nos and fuel solenoid, do they just hang off the lines?? (i.e. safe???) 2: where do I mount the purge kit, 3:also bought nos gauge and fuel pres. gauge but dont know where to bring those into the loop, 4: where's best to mount activation switch. i've got the bottle mounted nitrous line run, wot switch mounted and clicking but now i'm lost. i tried to check other posts but only confused myself worse. I bought a book but havent made it through 130 pages yet. hopefully i did mygarage right and it shows my mods. Please help and thanks, you'all always do!! Sorry for my stupidity, multiple contributing factors.
