jono Posted April 12, 2014 Share Posted April 12, 2014 Does it help you if you take into account the rubber intake boot has a junction at its base in the middle? Think one hose goes there at least. Not seen the cruise control before - is it factory ? My after market CC needs vacuum to keep cable pulled. That vacuum changes to pressure under boost, you have turbo - so, is there a separate vacuum making device like later Legacy turbos i believe, that you can hunt around for ? or does CC drop off under boost ? I'm considering will have to go electric next time around to cater for boost interference if it at all happens Quote Link to comment Share on other sites More sharing options...
Gloyale Posted April 12, 2014 Share Posted April 12, 2014 Vent line with the T goes into the small hole on the side of intake boot. 2 lines in the last picture with the spring clamps on the end.....these go to the Turbo.....One is pressure to the Wastegate solenoid....the other is Output to the Wastgate from the solenoid. Judging by the bend...the one in your hand goes on the port on Pressure side of turbo outlet. Not seen the cruise control before - is it factory ? My after market CC needs vacuum to keep cable pulled. That vacuum changes to pressure under boost, you have turbo - so, is there a separate vacuum making device like later Legacy turbos i believe, that you can hunt around for ? or does CC drop off under boost ? That's the dealer installed setup. There is supposed to be a Check valve and an extra resevior to work in the turbo models......Although....the extra canister is bulky, close to the turbo.....so it get's ditched.......or like one I've owned.....it catches on fire from turbo heat. I repaced it with a Knudsens Juice glass bottle with a hose shoved through the cap. It worked fine.....although on very long stretches I would occasionally have to apply some thottle then let off to create a bit more VAC to keep the resevior "full" (or empty?) of vacuum.

elgigante Posted April 12, 2014 Author Share Posted April 12, 2014 Thanks so much for the help. So the two lines from the solenoid go like this? Couple more thing. On the bottom of the cruise control unit, there is a spot for a vacuum line. Where does this go or "T" into? Also on the boost valve/solenoid the vacuum vent gets T`d into the big vacuum hose that goes into the intake. I have that but by looking at my pictures does that all look right? Also ontop of the boost solenoid there is another valve of some sort. I believe thisnis for the boost light? Does this just go straight into the intake manifold? 1 Quote Link to comment Share on other sites More sharing options...
