Re: BOV placement pics
RPM sells nice braided brakebooster hoses with a adapter for a boostgauge, i screw an adapter on it so it has 2 vacuum ports.
I wont recommed to T-it into your vaccuum line for your map sensor or FP regulator!

Re: BOV placement pics
There's a vacuum line that runs from the front of the intake around the passenger side and to the back of the intake. There should be a line coming off of this going inside the cab for the A/C vents, etc. T into that line for the BOV. Here's a diagram:

Re: BOV placement pics
A blow off valve typically doesn't need to see boost. It's job is to vent the intake charge back into the atmosphere or downpipe so that it doesn't hit the back of the turbo. A wastegate needs to see boost to bleed it off.
Some blow off valves can do both boost and vacuum, but most are vacuum only.

Re: BOV placement pics
I have neither as well, but I still have the line that goes from the front to the rear, in addition to the hard line going into the cab through the firewall to operate the vents. If you have none of this, you can tap into the line going from the brake booster to the upper intake, or as a last resort the line going to the FPR/MAP.

Re: BOV placement pics
I thought BOVs were supposed to see both. Boost pressure to help keep the BOV closed under boost conditions since there is equal pressure on both sides of the diaphragm and vacuum to help it open when you let off he throttle. I turboed my Eclipse and ran my BOV the same way and Evo does, right off of the intake manifold. Wastegate diaphragms don't like vacuum at all.
