the line from the wastegate on the turbo needs a vacuum signal either from the barb on the turbo inlet or the intake manifold(your choice, this is the boost controller line) another line from the intake to the BOV that your using, another line from the intake to the boost gauge, and a final one from the intake to the CF RRFPR(some of these things can be run off the same signal line, but I always reccomend a seperate line for everything except maybe the boost gauge) hit me up too thogh if you need help on anything, been there done that and hate the RRFPR/AOBE setup...it works but its not my cp of tea, its why my fuel is now controlled with a MegaSquirt....belive me, its not much more in cost and its a hell of a lot better(the wideband and laptop drive the cost up though, but if your planning on a wideband anyway....a laptop thats good enough can be had for $120 shipped on ebay)
