The V8 Owners Forum -

On my 3.9 EFI I've got a round metal disc attached to the dizzy( next to the thermostate housing ), believe this is for the air pipes

One pipe comes from the throttle body, which side should that go on ?

Should I have a pipe on the other side of the unit? If not should this be left open or blanked off ?

Thanks

There should only be one pipe connected, facing away from the distributor body. The other stub is a breather I believe.

Is there a small vertical pipe on the plenum right above the throttle butterfly?

Yes,pipe comes from top of throttle butterfly

That's the right place.
