single turbo 1JZ help

[madsupra88]

Hey guys im having trouble finding where these vacuum lines go or what to do with them since i dont have the twins anymore

^^ If i plug that, the car shuts off!!

^^^^ If i leave that line open the car idles perfect at 900 rpm, if i plug it idle drips to 3-400 rpm!!

^^ I dont know where this goes.

YES i have searched and loked at the diagram for the vacuum routing on the 1jz but since im single turbo now im a little lost. thanks.

first pic is your idle air, put a filter on it

second pic is vacuum signal for the BOV

third pic is map sensor signal i bieleve

yes, mkiiichip is correct. The first picture you - You put a filter on the ISC.
BOV vacum you can cap it off.
Third is for you MAP sensor.

Coolant lines for iac are small like 3/8 hose. You can see them in the first pic.
