i got a 91 fox with a hp stage 1 kit and im running a aem tru boost controler. i followed the vac diagram when i installed it and it doesent seem right. it wont idle without inpluggin one of the vac lines on the vac tree (mounted on the fire wall) so i called the guys at hp and asked them and they told me to hook it up like u would for an internal wastegate. just wondring if anyone has one of these on their fox and can gimmie some pointers. thanks.......

 

I run one , my car is a turbo ls1 but same deal..... It is very simple to run it goes like this :

line out of the turbo compressor housing gets T'd
One line from the "T" goes to the boost control solenoid port #1
Other line from the "T" goes to the bottom port of your external waste gate
seperate line comes from port #2 on the boost control solenoid and goes to the top port of your wastegate.

Done!
