Preparing to install new engine with TTI: questions

For me, once the driver side was more or less in position (not bolted on though), I got under the car and slid the number 7 pipe into place while a friend was holding the rest of it and being my eyes on lining it up. Then it took some work to move it around and sort of pound it into place. Putting something on the tube to lubricate it slightly was a big help as is is super-awkward to be trying to manipulate it.
