So I have a 2001 prelude with a aem ecu and its built for turbo I need to bring it back to stock to smog, so the first problem is I need a vacuum diagram I searched google and the forums and could not find anything, also I do not have the black vacuum box that goes under the intake manifold will it run ok temporarily until I get it?

 

You must have not searched hard enough lol here you go.

 

Thanks thats what i was looking for, im also having a problem with the harness im missing the plug that goes to the intake control solenoid vacuun box above the transmission bracket is that plug part of the engine harness or dash harness? My engine harness doesnt seem to be original it has a bunch of extra plugs by the transmission and it has 5 plugs that connect to to the dash harness instead of 4 that are on another 2001 harness i just bought any ideas?

 

Here is a pic of all the extra plugs on the harness thats on the car now, its a 5speed btw, is it possible this car was automatic converted to manual?
