While doing my swap with the intake manifold with the egr valve i notice that there is only one nipple (which is the L shape) under the throttle opening on my jdm motor. It seem to be missing the one next to it. While comparing it to my usdm motor there is two nipple under the throttle. The L shape and stright nipple. On the usdm motor the L shape is being block and the stright nipple is attach to the vaccum line that go down to a little black box. Should I attach the vaccum line from the black box to the L shape nipple and will that have a affect on my car? or is there a way to buy a nipple and plug it in the hole next to the L shape nipple?
