Please Help - Cowl Induction Wiring

I have tried to do the research and just cannot seem to get my cowl induction to work. I had someone originally do the cowl induction setup and he could not complete it in a timely manner so I ended up taking the vehicle back and now I am very confused.

The flapper closes when the vehicle starts but does not function when the accelerator is pressed. i have tried reading pas threads but just cannot get it, It seems like there should be some sort of connection coming from the fuse box to the pedal switch? Im so confused, a video or detailed diagram would be much appreciated.

My apologies in advance, I did try and research this before posting a new thread..

Please help!!!

Re: Please Help - Cowl Induction Wiring

Charlie,

The actual flapper is vacuum operated.

The electrical portion operates an inner door to protect the ducting when the car is off (the outer door, of course, will be open due to the lack of vacuum).

The vacuum line that feeds the actual hood mounted "pod" needs to connect to the check valve, and then ultimately to a manifold vacuum source.

NOT using the in-line check valve will result in operation like this:


Make sure the vacuum line is not pinched when the hood shuts.
