there was a vacuum line on the back of my LS1 intake for the climate control. however this vacuum hook up is not on the back of the LS3 intake so where do i hook it up too now????

An LS3 intake will not fit on an LS1 engine the ports are different.
LS1 cars have cathedral port heads and LS3's have a more traditional square port.
