So I'm a dummy.. I took off my check valves without taking a picture first. I think I've got it right based off logic, but if someone could check for me id really appreciate it. There are two, one behind the battery going to the solenoid and one going to the intake. If you could pop your hood and tell me which side black half of the valve faces, or take pics, I'd be forever grateful.

There are actually three. The line that goes to the intake is just clipped to it, no vacuum connection there. The third is right next to the brake booster. You can use that one for reference, but the light green side goes toward the IWE solenoid (and should hold vacuum when tested from that side) while the black side goes toward the engine (and should not hold vacuum).

Go to my Diagnostic post in the How To section and there are pictures there... page three I think.
