I almost have my rebuild ready to start. I have a few questions on some vac lines. Where do i hook up the switching actuator to? I have read that I have to use the check valve and solenoid. I have the rat's nest i removed. I see a check valve still on the rack. Do i use this one? Also which solenoid do I use? Does the solenoid need power? Any pics will help. Also where do these vac lines on my UIM go. I think i should cap them.
