JDM b18c (obd2a) going into a 98 civic ex (obd2a) using the JDM p72 ecu.

Just a couple questions.

Is there a cruise control vacuum port somewhere on the intake manifold? If so, where is it?

There was a loose tube hanging from the hook-shaped port on top of the intake manifold. I took it out and hooked my brake booster vacuum line to it. Is this correct?

Thanks in advance!!
 
Your motor might not have cc. You can just t into a similar place that the line was at on the D16 motor. Looks like #12 will be a good spot. #13 is your the intake valves, you will need to add the wiring from the GSR harness to the EX harness for this to work. There are a few plug that need to be changed also. An OBD2a GSR motor into a Vtec OBD2a Civic shoul be a 99% plug and play swap.
