Ok, now i have connected it this way: one nipple on the greddy(Pressure Source) is T'ed to the black box behind brake Master cylinder and Greddy's actuator nipple i plumbed to standard solenoid's wastegate hose, i cut off the standard solenoid's other hose's restrictor and put it back and unplugged the standard solenoid. Then i have left with one empty nipple which should be connected to plenum, where should i put it?

Thank you for these tips they will get me far in the process, just that if i have to blank the standard solenoid's intake manifold pipe and therefore can't use it in connecting the Greddy solenoid's intake manifold nipple where should i connect it in before TB's? Is there another line that is not already bled? Don't know but it seems logical to me to connect both of the standard solenoid's pipes in greddy's intake manifold and wastegate nipple's, greddy solenoid seems to be exactly the same but it needs pressure source to read boost compared to MBC which doesn't need to read the boost to adjusting?!

TB= throttlebody my bad!

So simply there is no idea of disabling the standard boost solenoid? I just T from the actuator hose which leads from wastegates to standard boost solenoid? Any good place to connect to the plenum, what you mean By TB's?

Hi! I am a newcomer to this site (Hopefully this thread is in the right place) and i already have a problem. The problem is my EBC, i did get it wired and running but the Greddy boost solenoid box (The one with 4 nipples, 3 on the front and one in the back) is just space science, i've seen a lot of discussion related to these issues but they never gave me an answer. I'd appreciate it very much if someone who knows and possibly has done this install would enlighten me a little. Ok, so the original RB26DETT Boost solenoid has 2 vacuum lines in it, one is for certain the actuator line but what is the second one? when installing the Greddy solenoid can i totally REMOVE the original boost solenoid? Greddy instructions tells me to connect nipple number one to INTAKE MANIFOLD, but for god sakes where? the second nipple to PRESSURE SOURCE, it maybe simple? And the third nipple should be connected to ACTUATOR... I know, that there is a vacuum line behind the plenum, which should be connected, would it be the one this device want's to a intake manifold nipple on the greddy solenoid? If anyone has done this the way it is working i'd appreciate a little help here, anyone has pics or something about the install? Most help would be if someone could tell me where to connect each Greddy solenoid's nipple AND if possibly the original boost solenoid is replaced by the Greddy solenoid. Thank you guys, in advance!
