So on the D16z6 block there are 2 coolant lines coming out of the main water pump outlet on the block. One goes to the EACV, and the other the passengers side of the intake manifold. My issue is that the D15b2 block only has one outlet on that main line on the block. I ran the EACV one to the main line, but I dont know where to put the other line in.

here is a diagram from an EG (d16z6) and some added MS paint for color.



If someone can tell me where to connect the "red" line, I would appreciate it.
