I have a 91 civic sedan with a b18b1 motor but an a1 intake manifold trying to find a diagram on how to hook up the vacuum lines. My car does not have a purge cut off valve on the firewall so I'm looking for how to reroute that I have seen multiple old threads where people say to do this and it is not necessary other than passing emissions and have photos of how to reroute it but are old and pics can't be seen anymore anyone know how to do this?

 

are either of these what you are looking for

Thanks for the reply unfortunately no but I think I have it figured out we'll see once cars going lol

 

Hey all still working on getting this car going haven't had alot of time to work on it. Currently working on wiring and I had to remove C1 and C2 and move them to B10 and B12 which should both be empty towards all of the diagrams I have looked at but B12 has a wire in it I believe it was white/red I can check again to verify when I can get back to the car. I have seen on a couple pages that it may be A/C which would be fine as I don't have A/C anyways. Would just like to clarify this before I remove it.

 

You have to remove it anyway... another distributor sensor pair of wires will have to be inserted into C1 and C2.

 

I understand that they need to be moved to B10 and B12 I have already placed the new wires in C1 and C2 I was looking for what the wire currently in B12 is so that I know what I am removing.

 

Remove it... tape it off... forget about it. It is of no concern.

 

Ehh works for me lol that's what I did

 

Well got the car to start for now. Currently throwing codes. One for the ckp so ordering a new dizzy as current one was just laying around wasn't sure if it worked or not, one for ect found out the wires on the plug got busted so redoing that plug now and one for map sensor.

Question I have is why I would still get the map sensor code when the one in it worked before old motor was pulled (car ran and drove no issues other than bad dizzy cap) and also tried another that worked when another motor was pulled so both should be good? I have checked my vacuum lines they seem to be right maybe diagrams wrong? Currently going from map to spot on b18a1 throttle body. Any help appreciated
