I am installing a GlowShift Vacuum gauge in my 2004 Maxx. I have not been able to locate the correct vacuum line to connect the gauge to. Does anyone know where the intake manifold vacuum is? A diagram or picture would be fantastic.

Follow the vacuum hose from the brake booster to the manifold. That will be a source of manifod vacuum. Sometimes one end or the other will have a capped fitting that will let you tap into it by just removing the cap and attaching your hose/device.
