Ok i installed my true dual a few months ago. I was lookin at it the other day and the pick up tube at the top of the header i believe i plugged the EGR hose over it and not the 5th/6th port tube. The actuator tube is the smaller one correct? And the EGR hose is bigger much like the air pump tube correct? Also With the header came a block off plate for my ACV i have been searching all day and there is no deff answer as to if i put this block off plate on my 5th and 6th ports will still work. also i would need to remove my air pump. But does anyone have a picture of which tube/hose to use and where it goes from the true dual header. I believe i just hooked it up right by taking a vacumm hose and putting it on the top of the nipple on the header and the other end on the long nipple just above one of the Actuators. Correct me if i am wrong.

ON your 88 car the ACV and airpump have nothing to do with the aux ports working.

Connect the small pipe on the new headers to the aux ports intake pipe near the rear aux actuator.

Before you do that, put a piece of vacuum hose on that small pipe near the rear actuator and blow as hard as you can. The two actuators shafts should retreat into the actuators, or at least start to retract into the actuators. It only takes 2-4psi for them to work.

The EGR hose is on the left of the engine so what you said made no sense to me when you mentioned the EGR.

State what year car you have when posting.

It sounds like you eventually connected the header pipe to the aux actuators right. Why don't YOU take the picture.

Ok so i guess i am confused as to what the thicker hose is for then, it was once connected to the split air pipe the one that is the biggest hose and on the top of the connection point. I just followed that hose and it runs into the back of the engine and i can remove it. I wish i could find my camera. Ill look around but there are 2 hoses that use to hook to the Split Air Pipe. One that is smaller that hooks to the actuators and one that is larger and assume it eventually leads to the EGR but idk.

There is no EGR hose. The EGR valve is on top of the engine block and has nothing to do with the split air pipe.

You're talking about the large (~1") hose that goes from the back of the lower intake manifold to the split air pipe itself. Air from the air pump travels through it to the main cat. There is a check valve in it, but that is not an EGR.

The small line that comes off of the split air pipe does in fact go to the aux port actuators, so that's all you need to consider when getting the ports working properly. The rest of it is strictly emissions related.
