Im installing my profec b spec II because my car is spiking hard... where did u guys put the hose through the firewall ??? through the engine harness or through the driver side???

 

mine is thru the pass side and sits in the glove box. be sure to not kink the hose.

 

mine was passed thru the engine harness

 

i found a easier way... just make a lil hole in the grommet that sits behind the left tire through the little triangle the harness goes through to the engine and i installed it in the bottom din... ill probably figure out a way to hold it in place... did you guys use the method that t's the wastegate and the pca...
