where do the vacuum lines go that come from behind the intake manifold (pipe#4) one goes to cruise control an the other?

 

Fairly sure that goes to vacuum hose #19. # 9 is resonator chamber Bs solenoid. #3 is resonator chamber B.

 

Thank you so much ive been looking everywhere for this diagram! So mine is missing hose#19+ everything thats after besides the resonator box(missing solenoids)will the car run with hose#19 plugged?

 

Yeah, its a resonator for intake noise attenuation. Usually when a CAI or SRI in installed most of that stuff gets tossed. Although I thought the solenoid itself was left hooked up. But if you are not getting any weird electrical or codes then you should be fine.

 

I have a 1981 Honda Accord and my pos has vauum lines are jacked up, swapped around and it runs like complete **** because of it. and sometimes it won't even crank at all. It leaves me stranded at the wrong times. Th diagram on the hood is a complete mess and it's just not easy to understand. Is there anybody out there that can make it easier on what hoses go where and to what part thy go too? Literally. Like this is ridiculous. Why in the hell would somebody make a vehicle like this.. ?
