Jetta Turbo Removal

I'm 3/4 of the way into replacing my bad turbo in 2003 1.8t Jetta. I can't find where the oil supply line bolts to the block, can anyone shed some light on this location? Is it better to detach from the turbo side? I can't see how you could ever spin a wrench on the turbo side because the manifold is blocking the banjo bolts. Thanks -john
