allrite guys, i have an external wastegate on a victory performance o2 housing. ive been trying to find pics of how the mbc is hooked up but am not having any good luck. does anyone have a good pic of where to hook up the lines. if read correctly, the nipple closest to the driver side head light hooks up with the top line from the mbc and the nipple closest to the exhaust manifold is vented? the bottome line of the mbc will tee into the bov correct? it would be great if someone could get a real pic of it, but for now i guess my art talent will be put to use, so could someone show me the correct route for the lines from the bov and the lines on the wastegate, thanks

Go from the nipple on the turbo housing/j-pipe to the nipple opposite the adjusting knob on the MBC, from the side nipple of the MBC to the waste gate. Do you really need a drawing to accomplish this?

Even though people source from the BOV, it is not recommended to use this line as it can actually over spin the turbo if you have boost leaks.

Run it to the side nipple. Leave the top one open to the atmosphere.
 
BOV = To your Intake Manifold
MBC Top = To the Bottom of the Wastegate
MBC Bottom = To the Turbo Elbow or Compressor Cover

Wastegate Top = Leave open to Atmosphere
 
DO NOT pull from the BOV line to the manifold. I learned this in a not so good way.

I ended up overboosting my 14b because of a boost leak and a pre turbo exhaust leak. the turbo is ok for now, but it's not a good place to pull.

pull from the comp housing or the comp housing elbow. youll also ### down on a lot of vac hose this way, and it safer and more accurate.
 
I would recommend tapping the compressor cover on your 57-trim and getting your boost source there as apposed to T-ing into the BOV line. Also, make sure you use the side port on the external gate.

PS - I love your artwork - especially the cast looking exhaust manifold.
