I have a question on the IAB. The plug has two wires. I need to know which wire goes in the ecu and were the second wire goes too.. Do I just plug one wire into the ecu and the other wire I just ground it?? Also as for the IAB vac lines does anyone have a picture of how they're suppose to be connected.
Please help.. I have a 1998 b18c1 with an ex wire harness and everything is obd2. Thanks in advance.

The typical Honda way to do that stuff is one side of the solenoid is powered from the main relay at all times. The other wire goes to the ECU, which grounds it when it wants to energize the solenoid.

Go to acuraparts247.com or someplace like that, put in the car's information. I guess that would be a '98 Integra GSR since that's where the engine came from. Select intake manifold or something like that for a parts drawing. I'm pretty sure one of those parts drawings shows the IAB vacuum hoses.

You will need the vacuum tank that is designed for use with the IAB system. It is a small vacuum tank that mounts underneath the IM... If u look at hondaautomotiveparts.org you will see the vacuum tank on the drawings...
It WILL NOT work without the tank, believe me I tried to hook it up without one for a long time...

I think I can upload a picture of the IM hosing. Don't forget the check valve on the line going into the black vacuum tank. I think the tank cost $30+ but the solenoid is "outta sight". Let me see if I can get this pic:
NOPE, picture is on the wrong side. sorry.

OK go to the site and under the systems list click on the "vacuum tank" picture.
