ATI procharger question (s)

Dove into the prep part yesterday and noticed that the 2 hoses in the front that are to be relocatedt hat shows in the manual are no where to be found on my car? Is this cause I have a sedan. I have both the 350z and g35 manuals and it says the same for both. BTW I have a 04 AT sedan. Probably more questions to come but that was the main one as of 2 hours into the install.

New problems after the install complete. Already did a search.
These are procharger specific questions:
1. It seems to not building boost. I looked at the FMU and after a rev there are no lights lighting up and no increase in fuel pressure it just stays at 55. The boost guage reads past 30 vacuume at rest and revs up to 0 boost( havent herard the bov 1x yet) when getting on the gas. I rechecked everything and there are no leaks anywhere.
2. Also the rubber hose that comes off the blower does not seem to match the pics it comes out further. In the picture it looks as if it almost comes straight down. This is making both rubber hoses meet at the same point causing rubbing in the wheel well. Am I missing something?

Found this and will try it in the morning:

Good way to check if you have a vacuum leak within the vacuum tree as well as your boost sense and surge valve lines.

take off the hose that goes into the Intake plenum. the hose clamp is the one in the pic below.

Take that hose off and turn your key on. Blow into that hose. If you hear any air leaking try to isolate it. Also if you blow hard enough with your key on you should hear your aux fuel pump kick in.

If air leaks out fix the leak, if air doesn't leak out and the fuel pump doesn't kick in you've either got a crimped hose, blown fuse that connects the FMU to the battery, blown fuse for the cigarette lighter, bad fuel pump, or blown FMU.

Now suck on that hose, if you listen very carefully you should hear your surge valve open. The surge valve is located behind the bumper on the drivers side. It should be directly below your headlight. If you can't hear it, maybe grab someone to put their ear up to the bumper. If you suck hard enough and then release the pressure you should definitely hear it clunk back into its original position. Ensure that when you suck, the vacuum stays the same. What I mean is if you suck and then put your tongue to block the hole in the hose, you should not feel any lessening of vacuum suction on your tongue.

If you feel a lessening of pressure you've either got a loose connection, leaky hose or bad surge valve canister. If you don't hear anything at all your hose is probably crimped, or the bypass valve lever is being blocked from allowing the valve to open.
