Default AirGap Vacuum port for headlights?

Hey where do you guys with Edelbrock AirGap intakes install your plug for vacuum to operate the headlights? I have a BB so if any of you have a pic that would be great!

Thanks
Wade

a TEE at the back. mines a 3 way . 1 port to lights, 1 port to pcv and the other i have bunged off..... although i was fiddling with vacum lines myself when this picture was taken so it may not look like how i described in the picture but you can still see the lights vacum line shooting off to the left.

So you are porting your pcv into the manifold and not the back of the carb??? I don't have a wiper door so I just need the port for the lights and if it is a better option I will port the pcv to the intake.

Thanks

Cool thanks for the info! I am running a hydroboost setup so I don't have the vacuum line for the power booster.

sweet as. you can go either way then but you might as well make use of that carb vacum . i believe its the most vacum so it should speed up your pop up time if you go there.

You should never run your PCV line to a vacuum port on an intake runner.
You will make that cylinder run way lean.

I always put the PCV on the carb port and the brakes & lights on manifold vacuum.
