As title

1 when hooking up my boost gauge do i tee in to the vacum tubing comming from the fuel regulator or the one comming out of the top of the dump valve

2 the only wire i need to hook up is the green which goes to the live on the coil but i have now fitted a wasted spark system and need to know which wire to hook into there are two black and one red entering the coil pack
am i right to assume it is the red one

Help appreciated
