i havea 2006 wrx and i have bought a boost gauge and i dont know what 2 splice and or where 2 connect what for the boost gauge... im new 2 boost so a couple pics or something would help very much. i dont wanna screw something up lol

 

tap into the the BOV. don't cut the line, add a small T and put a short piece to the BOV and the open end to your gauge. if you don't want to do it there you will need to find an intake manifold source, ie. anywhere behind the throttle body.
