Default B18A1 in a 1990 Si Rex HELP, Vacuum Lines ? ? ? Pics Inside!

basically i got the rex like this and all the vacuum lines were either wrong or messed up so i pulled them all off.

i found the wiring diagram for a LS and for a CRX Si and i noticed the part that all the vacuum lines go to that is mounted on the firewall is different from the Integra and Rex.

please tell me whats wrong and the ones with the red circle im not sure what goes there, or if anything goes there, or if it needs to be capped off or left open. and i believe the vacuum lines by the FPR is wrong too.

And also there is a red circle above the charcoal canister well i tried to take the old vacumm line of it and it snapped some of the charcoal canister too about the red lines so do i need to cap anythin of since there is no line coming from there.

thanks all help is appreciated.

I'm guessing the dashpots need to be T'ed, but in retrospect, you do not need them.

the 2 on the IM run to the intake, you are using a CRX intake pipe, hence the reason it is lacking them, it looks like you are using the wrong solenoid on that firewall

what answers are you lookin for?

you are using the wrong map sensor and purge solenoids

the 2 circles on the IM go to the intake pipe, you are clearly using a CRX one which is the reason you dont have anywhere to run those hoses

code 10 is your IAT sensor, on the runner farthest to the right if you are lookin at the engine from the radiator
