Got my boost gauge today

Well I got my boost gauge in. I will need to be walked through the installation definitely. It says the 1.5' hose they sent me with it needs to go to the fuel pressure regulator. Where is that? Also need to know where a hose can connect to the intake manifold, doesn't show where just has a pic of a hose and an arrow and says "intake manifold." Only other things I need to know are wires for the following:

Power(Got it)
Ignition line
Parking light
Ground(got it)

Any and all help with this would be greatly appreciated. Thank you.

Parking light: I tapped mine from one of the wires going to the headlight switch so the light would follow the instument cluster lights.

I'm not too sure on the light wire but I know I can figure that one out. Where is the fuel pressure regulator guys and where would a hose attach to the intake manifold? Thanks alot.

The vacuum hose has to hook up to the intake manifold or somewhere else that will have the same pressure as the manifold. Basically tee into any vacuum line, but not one that only sees vacuum, or only sees boost like one of the pressure tanks, or check valves.

The parking brake wire on my '90 TII at the headlight switch is red with a white stripe. I was just in there last nite replacing my speedo cable - now I have speed-sensitive steering again - what a difference.

Where should I hook it up to though? Any pics would be great.

Off the subject watch that 3' downpipe/midpipe. If your getting all these parts in a few weeks, think about investing in some bigger injectors, haltech. Crazy boost creep is coming for you with that setup.

Well I am going to have a larger fuel pump in and an s-afc to control it. I still will have my stock catback and I can put my stock intake back on if I boost too much. I know I don't need a haltech, not until I get a full turbo upgrade.

I tee'd into the boost pressure sensor vac line because it's the easiest line to get to on a RHD car. On a LHD car you might find something easier to get to on the left side of the engine bay.
