vac line Q,s

[Shabbernigdo]

i just need to know does the FPR and the secondary butter flies actuator just need a constant source of vaccume to work? I see that they are hooked up through silonoids and im wanting to get rid of the rats nest of vacumme lines on the back of the block so i just need to make sure they only need constant vacumme to work properly or do they have to be controled through the silonoids?

this is on a 91 ka24de.
