Getting the Stock Boost Solenoid To Work.

[BlackTruenoAE86]

Hey guys, I have a Red Top SR with FMIC and other mods and was wanting to try to run the stock solenoid which should bump up the boost to 10-11psi. So my brother in law had one lying around and I decided to hook it up. I ran the vacuum line from the waste gate to the the vacuum source and drove it around it shot up to 17 psi or something So i thought I had the hoses backwards so I switched them and it shot up to 17 psi again, does something else need to be hooked up, I haven't checked if I'm getting 12v from the plug yet. Is there a specific way I have to run it. I tried looking for the stock vacuum diagram but had no luck.

Thanks,
