I just swapped an ls into my 89dx and i used the LS map sensor/solenoid cluster.

I only hooked up the MAP so the other to purge valves are disconected, they have vacuum going to them but they are disconected.

I want a vacuum diagram for a 91 ls, and I want to know what 2 things are.. a. the piece on the t/b that hooks into the throttle cam and uses vacuum, and b. the other unit that sits in the middle of the manifold and says "UP" and has 2 lines going into it.

Also how do I hook up those valves? I only use ne now right? DO I re-use the dx one? And just attatch the LS map to it? Please help this bitch barely idles!

 

help!

 

Here you go dude, this is the diagram that the state ref gave me to refer to after I passed smog. The '90-'91 have the same layout. Hope this helps...

word thanks.. a couple questions..

what does the air boost valve do?

and Which one of those solenoids on the firewall do i hook up? Or do i use the dx one?

 

noone knows?

Hook up all of the solenoids, make sure the smog stuff you have is for a 90-91 Integra though.
