Embarrassing N00b Question

[ctnewman]

I pulled the motor out of the car 3 years ago... I probably have pictures at home where this goes, but maybe you can help me out.

There are two coolant lines open towards the back of the block. One of these connects to the coolant pipe under the manifold, one connects to the pipe that eventually joins the thermostat housing between the pump and thermo...

I know one of them connects to the coolant exit from the turbo, but where does the other one go?

Or do they tee together and then connect to the turbo?

My "double vacuum pipe" is AWOL, so I cannot verify it with that...

You can see the two open coolant lines in this picture:

can someone just post a pic of the back of a stock rb26?
